Clutch Materials FAQ

No Comments

Q.What are the various clutch materials? clutch materials
A.1. Organic
  2. Kevlar
  3. Ceramic
  4. Feramic
  5. Carbon (initially invented in 1998 by Alcon Components for the Subaru World Rally team

Q.How does it work?
A.A traditional manual clutch uses springs to push a pressure plate into the clutch disks to keep the clutch always engaged until the rider pulls in the clutch lever, pushing the pressure plate away from the clutch disks to manually disengage the clutch.
An automatic clutch keeps the pressure plate away from the clutch disks when the engine is off or at idle. When the throttle is applied and the engine speed increases, a centrifugal device within the clutch expands, engaging the clutch disks.

Q.What is an automatic Clutch?
A.An automatic clutch is “automatically” disengaged when the engine is at idle or off. When the throttle is applied and engine speed increases, the clutch becomes engaged automatically.  An automatic clutch does not change the way you shift gears; it simply prevents the engine from stalling by automatically disengaging.

Q.What performance advantage can a Super Clutch Racing clutch give ?
A.Super Clutch Motor Sport clutches are intended for all forms of Racing & Rallying. They are optimised for compact dimensions with associated low weight/inertia to enable improved engine response and quicker acceleration due to reduced flywheel effect. Generally, a more effective improvement than searching for the ultimate in engine power.

Q.What is a “Paddle” type clutch disc?
A.Simple system superseded by modern high thermal capacity fully bonded 3600 contact systems. Originally to upgrade standard clutches for higher temperatures. Can create rapid wear and give rough clutch engagement. Usually resembling a flattened three blade propeller with small pucks of metal friction material riveted to a clutch disc centre.

Q.What is the best Motor Sport clutch for my application?
A.Only the customer can select the most appropriate match with their requirements. We offer comprehensive choice, plus supporting information, data and motor sport experience
clutch materialsQ.What is a dual friction clutch?
A.A dual friction clutch is when two different friction material facings are applied to each side of the clutch disk. For added performance and service life, Kevlar is added to the pressure plate side of the clutch disk and the other side remains organic. For street and strip, a dual friction disk is often a combo of Kevlar and metal. The one flaw in this logic is that your overall holding power is then limited to the weakest holding material.

Q.What causes my clutch to chatter?
A.Some of the more common reasons for clutch chattering are:
- Clutch controls are improperly adjusted. Frayed or stretched clutch cable.
- Burnt or glazed friction plates.
- Worn or warped friction plates.
- Diaphragm clutch spring does not have enough tension. Too flat or worn out.
- Clutch hub liner friction plate rivets loose or broken.

Netbook FAQ

No Comments

Q.What is a Netbook?Netbook
A.Basically, it is a small computer, often marketed as a web-device but actually capable of doing everything your desktop or notebook computer can do. It is, in all respects, a standard PC.

Q: What is Windows CE?
A: Windows CE is Microsoft’s operating system for minimalistic computers and embedded systems. Windows CE is a distinctly different operating system and kernel, rather than a trimmed-down version of desktop Windows.

Q.What are the advantages of a Netbook Computer?
A.The advantages of a Netbook Computer are:
1. Price – apart from the more specialist machines, Netbooks are becoming the cheapest PC platform.
2. Small Size making it easy to use on the desk.
3. Screen quality – LED vs. LCD Technology
4. Very Light – weighs a Kilo or less, which is a bag of sugar. A standard laptop weighs at least 2 or 3 kilos, sometimes more.
5. Portability on account of its small size and weight
6. Longer Battery Life most netbooks have good battery life

Q.Is a netbook for me?
A.Netbooks are aimed at people who need ultra portable PCs. If you are looking for a light weight machine to access the internet on the move, around the house, in the garden or need something you can take to University then you may well love a netbook!

Q.What can’t a netbook do?
A.Next generation netbooks are fully functional computers. Some heavy weight professional applications may not run well and remember that they necessarily have small screens, but otherwise netbooks are not toys, they can run most things that the average user will need.

Q.Are Netbooks a passing fad?
A.Not at all, light weight portable PCs are here to stay, whether the name sticks or not is another question but if you like the look of owning a PC that you can easily take anywhere then you’ll love owning one of these. The first models hit the scene back in 2007 and new netbooks are hitting the shops every month.

Q.What about the small screen ?
A.First of all, Netbook screens tend to be run on LED technology whereas most notebooks and PC monitors are LCD. What this means is that a 10.2″ or 8.9″ screen will appear just as sharp and usually brighter than a larger LCD equivalent. The resolution is smaller (1024×600 instead of 1280×1024, 1024×800, etc.) but importantly not widthways, so most things we work on are just as readable. 7″ screens take slightly more getting used to on account of the size but nevertheless they are very usable, with crisp easily readable lettersand graphics. A 7″ screen becomes much more usable if it can be rotated to portrait view, such as with the Samsung Q1 Ultra or the Vye S37 and S41. Then a whole A4 page is easily viewed and with a touchscreen, as both these examples have, documents such as PDFs and other touchscreen-friendly applications can be finger-scrolled, making them emanently usable.

Q.How to improve the performance?
A.One of the most cost effective way of improving the performance of your netbook is to upgrade the internal memory of the netbook.  Not all netbooks will allow this as some of the memory is non removable and some are fitted with the maximum memory that the netbook can take.  To check the memory on your netbook we recommend you do a memory scan from crucial memory.  http://www.crucial.com/uk/systemscanner/index.aspx find out if your netbook can take more memory, normally means removing the memory card that’s in the netbook.

Q.How to proect your netbook ?
A.How to protect your netbook while you travel is a question every netbook user will ask themselves at some point. There are a few different methods of protecting your netbook while you travel and two of the most common are to get a netbook case or a netbook bag. 
here are many different types of netbook case on the market and it all comes down to user style and preference.  Ultimate-Netbook supply a range of dedicated leather netbook book sytle cases which are custom made to fit your netbook.

Solar Panels FAQ

No Comments

Solar PanelsQ.What is solar energy?
A.Solar energy takes advantage of the sun’s rays to generate heat or electricity. It is an infinitely renewable resource and unique for its ability to generate energy in a quiet, clean, and consistent manner. Can’t beat the sun for being oh-so-cool!

Q.What is the difference between solar panels versus building integrated photovoltaic products?
A.Solar panels are flat panels of photovoltaic arrays mounted on a roof or a pole to capture the sun’s rays. Building integrated photovoltaic materials are PV arrays that are integrated into the building material itself, primarily windows, roof tiles, or walls. Solar panels work well for retrofits or remodels while BIPV are appropriate for new construction or a major renovation.

Q.What solar panels CAN do?
A.Solar keeps an abundent supply of hot water in your hot water tank, thus extending the life span of your boiler because for most of the year, your boiler will not be used at all.
From March – September, solar will do most of your water heating needs, and then half that in the winter.

Q.Is my home suitable for solar panels?
A.If you have a South/South East/South West facing roof space, then your home is suitable. Your internal electrical or plumbing set up will need to be checked for compatibility and this can be done through our free home survey and ‘get a quote’ service.

Q.Free solar panels offers, what the catch?
A.The easy way to answer this, is what is the company offering the free solar panels gaining? The answer in short is your 41.3p per Kw incentive. They will be using your roof to take your grant off you. This is the equivalent of taking your chicken lunch off you and throwing you the wish bone to chew on. You will wish you had installed them yourself.
Yes you will get small savings off your electricity bill, but you will loose out on the thousands of pounds government grant.

Q.Can solar panels add value to my property?
A.Yes, your homes value will increase in todays climate of high energy pricing.
A recent survey by MORI found people are willing to pay up to £10,000 more for a home built to high energy efficiency standards and estate agents have been raising the value of properties with solar panels compared to those without.

Q.How do I know if solar panels will work on my home?Solar Panels
A.Take a look at the position of your home on its lot – and particularly your roof. Ask the following questions:
Is there good southern exposure? Orienting solar panels to the south maximizes the effectiveness of energy collection.
Is the exposure free of trees or buildings that could shade the panels or drop debris on them? Shading photovoltaic panels dramatically reduces their effectiveness.
What is the pitch of your roof? Most roofs, from flat to 60-degrees can accommodate photovoltaic panels.

Q.What other factors are important to consider when installing a home solar energy system?
A.The location of your home and the local climate will play into where you place and how you install your solar electric or solar hot water system. Wind speeds, heavy snow loads, and salt water can all affect a solar array. Understanding how those inputs effect performance will determine the types of mounts or how the arrays are angled. A solar pro in your area is likely quite knowledgeable about your local conditions and can help you design that works well for you.

Q.There are 2 types of domestic solar panels, which is best?
A.Both do very different jobs with different pricing structures:
Solar heating panels including evacuated tubes (heat generating)
PV electric solar panels (electric generating)
Which you choose varies per household, but it basically depends on which type of energy cost you want to reduce and how much money you can afford to spend. People now see solar panels as an investment into your home and energy future.

LED Tube FAQ

No Comments

Q.What is a LED Tube? LED Tube
A.LEDs differ from traditional light sources in the way they produce light. In an incandescent lamp, a tungsten filament is heated by electric current until it glows or emits light.
In a fluorescent lamp, an electric arc excites mercury atoms, which emit ultraviolet (UV) radiation. After striking the phosphor coating on the inside of glass tubes, most of the UV radiation is converted and emitted as visible light.
An LED, in contrast, is a semiconductor diode. It consists of a chip of semiconducting material treated to create a structure called a p-n (positive-negative) junction. When connected to a power source, current flows from the p-side or anode to the n-side, or cathode, but not in the reverse direction. Charge-carriers (electrons and electron holes) flow into the junction from electrodes. When an electron meets a hole, it falls into a lower energy level, and releases energy

Q.Will the person get electricity shock when installing the LED tube?
A.UL and MET certification organization has recognized this matter thus DIGOLIGHT tube has already changed to new design to have only one-end AC INPUT,  which does the same like conventional T8, no one will get shock at the other end when during common-sense installation

Q. What are the advantages of LED tube lights compared with conventional incandescent lights?
A.There are several obvious advantages of LED tube lights have over traditional incandescent lights, they are as follows:
• Low power consumption – energy saving;
• Long lasting,
• Cold lighting,
• Ruggedness,
• Small size and light in weight,
• Fast switch times,
• Simple to use.

Q. Do LED Tubes contain hazardous chemicals?
A. LED tubes contain no hazardous chemicals. It is a little-known fact that many Fluorescent tubes contain Mercury and Phosphor. If a tube is broken, the potential for poisoning exists, especially if proper clean up procedures are not followed. Because of the relatively short life of fluorescent tubes, their collective impact on the environment can be significant.

Q.Do LED Tubes flicker or emit ultra violet?
A.LED Tubes do not flicker. The light emitted by an LED tube is very stable and produces no side effects. The “color” of LED tubes is 5000K to 6000K.
LED  tubes do not emit ultraviolet. The level of UV emitted by most fluorescent tubes is so low as to be irrelevant. Tests indicate that 8 hours of exposure to the UV light emitted by a fluorescent tube is the equivalent to two minutes of midday sun.
Q. What does LED TUBE T5,T8,T10 mean ? LED TUBE T
A. Technically, any LED tube T must be named with a number. Figure represents one-eighth inch in diameter, so we are most familiar one inch LED  tube called T8.
T10 means is that the diameter of fluorescent tube 10 / 8 inch, said that T10 is the thickness of LED in terms of its diameter is 1.25 inches.
T5 will be obvious meaning is the diameter of 0.625 inches of LED tubes.
Q.What do “cool white” and “warm white” mean, and what is CCT of LED tubes?
A.The Color Correlated Temperature (CCT) is given in the description of each of our LED tubes. The color (CCT) of our LED tubes ranges from a warm yellow white (2700K) to a cool blue white (7500K).
Q.Are white LED tubes dimmable?
A.Dimming LED tubes depends on the design of the product, Since LED tubes are current driven devices, and it is not advisable to lower the voltage in order to dim a tube. Dimming does not lower the lamp life of the LED tubes and can often increase it.

LED Light FAQ

No Comments

LED LightQ.What is an LED?
A.LED stands for Light Emitting Diode. No filaments heat up, as in traditional lights. Instead the light is created by a cleverly designed tiny electronic chip.

Q.Where can I see LED lighting today?
A.The first LEDs were not very bright, and were used primarily as indicator lights on electronic devices.  Today’s high-brightness LEDs can be found in a wide number of consumer applications.  These include backlighting for color displays in personal electronics (e.g., cell phones), automotive interior and exterior lighting, traffic signals, large-area outdoor displays (such as those in New York’s Time Square, or along the Las Vegas strip), channel lettering (replacements for neon-tube signage, architectural accent lighting, etc.).  LEDs emitting in the ultraviolet (UV) wavelengths are finding use in a wide range of environmental applications (e.g., water purification and biochemical detection), as well as in medical devices.

Q.Why should I pay more for LED lighting?
A.The LEDs have a very long life, do not need replacing, consume a fraction of the electricity of incandescent bulbs, and are not nearly as subject to voltage drop. Payback is around two years of saving electricity and bulbs.

Q.Could you give more detailed explanations about these LED advantages?
A.Yes. Currently available LEDs are more energy efficient than incandescent bulbs, but less than florescent bulbs with the same light output. The power consumption of popular LEDs ranges from 30mW to 200 mW.
People can save money & energy by using LEDs instead of equivalent incandescent decorative bulbs.
he rated average working life of LED is 100,000 hours compared with 1,000 hours of incandescent bulbs.
LEDs emit cold lights as working LEDs generate very small amount of heat, so LEDs are much safer than equivalent incandescent light bulbs in terms of danger of fire. LEDs don’t have filaments to heat up in order to emit lights just like the case of incandescent bulbs. Lights are emitted from LEDs as a result of energy exchange occurring in the different semiconductor materials an LED is made of.
LEDs are usually shielded with solid transparent plastic materials so they are more rugged than incandescent and florescent bulbs that are usually sealed with glass.
LEDs can be powered by either AC voltage or DC voltage. The circuit that is required to appropriately drive LEDs is much simpler than that for florescent bulbs.

Q.OK – that all sounds good. So how does the light compare?
A.LEDs gained a reputation a few years ago for having a weak light output which was often blue in appearance. No longer. And certainly not from Eo Lighting. We are at the forefront of this technology. There are many lights in our range which are a warm white, echoing the light of a halogen lamp. LEDs are able to be coloured  precisely – much more precisely than any other lights. There are two ways to achieve this: for a high powered single LED chip, a coloured phosphor is coated on the silicon chip. For a cluster LED, the cluster can include red, green and blue chips. These can be adjusted to match most colours.

Color LEDQ. why are LEDs of some colors are more expensive than LEDs of other colors?
A. the reason is that different semiconductor materials are used for different color LEDs, and some semiconductor materials are more expensive than others; another reason is that manufacturing costs are different. White LEDs are the most expensive because red, green and blue LEDs are combined together to make a white LED.

Q.Why wouldn’t I just use an LED MR16 replacement lamp?
A.While these lamps have improved dramatically over the past several years, they still have one insurmountable limitation. They can’t be much bigger than a halogen MR16 lamp. Therefore, with LED MR16 replacement lamps, the heat sink has to be very small. By comparison, with our LED heads, the entire head can act as a heat sink. This means you can use higher wattage LEDs and drive them much harder to maximize light output.
That being said, there are applications where an LED MR16 replacement lamp would work just fine and we could recommend them for use in our low-voltage fixtures.

Q.What do “cool white” and “warm white” mean, and what is CCT?
A.The Color Correlated Temperature (CCT) is given in the description of each of our white led bulbs. The color (CCT) of our white bulbs ranges from a warm yellow white (2700K) to a cool blue white (7000K).
By comparison, a typical incandescent bulb has a CCT of 2800K. A typical halogen is a bit higher, maybe 3500K. Daylight white is 4500K and a cool white fluorescent is 6000K or more.
The human eye adapts to background light so that even a daylight white bulb will look slightly blue in a room illuminated mainly with incandescent bulbs. Similarly, an incandescent bulb will look very yellow or even orange in midday sunlight.

Q.What are the environmental benefits?
A.22% of the electrical consumption in the USA is used on lighting. A substantial amount of energy can therefore be saved by converting to LED lights. Since the primary source of energy in the USA is the burning of fossil fuel and thus generation of CO2, the environment will benefit from a reduction in the amount of CO2 emitted for every kilowatt of energy saved. Every mW-hr of electricity saved will reduce CO2 emissions by 1 ton. Excessive CO2 emissions are a key reason for the partial destruction of the earth’s ozone layer and onset of global warming. Landfills will also benefit from the implementation of LED lighting due to the long useful life of the LED lights. One LED light can last has long as 50 conventional incandescent light bulbs. This is a true savings of waste.

Q.What type of voltage and current do LED lights require to operate?
A.Conventional incandescent lamps are made to operate on standard AC power. Descrete LED chips themselves are designed to operate on DC current typically in the 350 mA range. As a result LED bulbs are designed with built in AC to DC converters that supply the correct current needed for the specific LED chips. LED lights may be used in place of traditional incandescent lamps without changing the fixture. Please note that most LED lights are not designed to be used with dimmers. Do not install an LED bulb into a dimmer controlled circuit with a properly designed LED lamp.  Flourescent Tube lamps operate with a specific ballast.  To install a T8 LED tube replacement, the flourscent ballast fixture must be removed or bypassed to provide the standard direct connection of the 110 VAC power to the T8 LED tube.  One end of the tube receives the positive and one end receives the nuetral.

Tennis FAQ

Q. What is the Origin of Tennis?
A. Amazingly, the historical development of tennis dates back several thousands of years. So, people who are involve in historical researches of this great sport claim to have found evidencetennis of playing tennis in ancient Greece culture.
The History of tennis game was developed from a  12th century French handball game called “Paume” (palm). In this game the ball was struck with the hand. After some time “Paume” game produced handball “Jeu de Paume” (game of the palm) and there were used racquets. The game was first created by European monks for entertainment roles during ceremonial occasions. At first, the ball was hit with hands. Later, the leather glove came into existence. This leather glove was replaced with an adaptive handle for effective hitting and serving of the ball. That was a birth of tennis racquet.
Development of tennis racquet , tennis balls also underwent  frequent modifications. First tennis ball was from wood. Later in the history of tennis ball was filled with cellulose material to gave way to a bouncier. Monks from all areas of Europe favored “Jeu de Paume” game during 14th century much to the chagrin of the mother Church. The game spread and evolved in Europe.
The game became very popular, especially in France, where was adopted by the royal family. In the year of 1316 French king Louis X dies after hard  “Jeu de Paume” game (other terms of  this stage of game are Royal Tennis in Great Britain, Royal Tennis in Australia, Court Tennis in the United States), but this death does null to damp the popularity of the recreation.

Q. How to play Tennis?
A. To properly learn how to play tennis, it is best to go out to the tennis courts with an instructor or a friend that already knows how to play and who can give you some pointers. Of course, if you want to get a good idea as to how to play tennis before you hit the courts, here are some pointers:
The main pieces of equipment needed when learning how to play tennis are tennis racquets, tennis balls, and a tennis court.
A regulation tennis court as a few different lines on it – the tennis net goes across the very middle of the court. The closest parallel lines to the net (on either side of the net) are called the service lines. The parallel line furthest from the net is called the baseline. The two long strips on both sides of the court, perpendicular to the net are called the alleys.
In singles tennis, the alleys are considered “out” – if the ball bounces in them, it does not count. In doubles tennis (tennis with two teams of two, one team on each side of the net), the alleys are “in.”
tennisA game starts with a serve. The serving player starts behind the baseline on the right-hand side of the court (his right-hand side) and hits the ball into the service box on the other side.
The service box is the box on the opposite side of the court – both over the net, and on the server’s left-hand side (the returner’s right-hand side). The service box is between the alley and the middle of the court, between the service line and the net. The ball must bounce once in this box for it to be considered a good serve.
If the server misses the box, he gets one more chance to get it in. A server always gets two tries. If he misses, it is the opponent’s point.
If the serve goes in, the person returning must hit the serve either before it bounces (if he knows that the ball would be in) or after it bounces once – if it bounces more than once, then it is the server’s point. The person returning must hit the ball over the net, and it can bounce anywhere on the opponent’s side of the court (remember that the alleys are out, though).
The two players hit the ball back and forth until one person misses – either by missing the ball when it bounces on his side, or by hitting the ball out of bounds onto the opponent’s side. The person who did not miss gets a point.
The server switches sides for every serve – the second serve will be served on his left-hand side of the court and into the opposite side service box (on the opponent’s left-hand side).
This article on how to play tennis will not get into scoring (love, fifteen, thirty, forty, deuce, etc.) except to say that a player wins a game after scoring at least four points and wins by two.
The next game, the other person serves and they continue to switch off, game after game, until someone wins the set. Generally, to win a set, a player must win at least six games, and two more than his opponent.
A match is made up of a number of sets (often 5 or so), and the player that wins the most sets wins the match.
These are only the basics on how to play tennis. Again, if you really want to learn how to play tennis, it is best to go out and play with someone who already knows how. Although, it can be very fun to simply go out and hit a few balls back and forth with a friend, regardless of whether or not you know how to play tennis properly.

Q. What’s the best type of tennis racket equipment for a beginning, intermediate and advanced adult player?
A. The two primary measurements of tennis rackets are power and control. These are the yin and yang of tennis racket design. The perfect balance of power and control for one player will be totally wrong for another. As a general rule, however, you can say that beginning players have smaller, more hesitant swings that dotennis not generate lots of power. Beginners rely on the racket to generate this power for them and therefore need a racket that has a high power rating.
Conversely, you can say that advanced players have bigger, more aggressive swings that generate lots of head speed and power. They don’t need a racket with a high power rating since they are doing this work themselves. What the advanced player needs is a racket that gives them more control over their shots.
Another basic tenet of racket design is that bigger racket heads give more power, and smaller heads give less power. Power is affected by many other design elements as well, but you can use this basic principle to start your search for the perfect racket.

Q. Why are tennis rackets made of graphite and titanium composites instead of wood? Where have all the wooden tennis rackets gone?
A. Weight, strength and speed are the names of the game in tennis racket design. Graphite, carbon fiber and titanium are the most common materials used in tennis rackets today (aluminum is still used in very low-end rackets as well). These high-tech materials cost less, are stronger and more versatile than is wood, lending greater creativity to racket designers and a much broader selection of products for players.

Q. What is the history of wooden tennis rackets?
A. Early racquets date back to the 14th and 15th centuries and were used in games that resembled squash more than modern-day tennis. The heads of these racquets were more oval in shape and smaller than today’s racquets, and the handles were very long. The game of tennis as we know it today and its equipment got started in the late 19th century in London, England. In 1874, Major Walter C. Wingfield patented the rules and equipment for a tennis game played outdoors on grass lawns. From 1874 to 1967, tennis rackets were made of wood and did not change very much in design, though their construction improved dramatically.
Rather than craft a tennis racket out of large pieces of wood, lamination allowed racket makers to glue layers of wood together. The wood tennis rackets of the period were heavy (many weighed in at an impressive 14 ounces), lacked maneuverability (thanks to their weight and balance) and were low in power (the head size was only 65 sq. inches).
Then came the T2000 from Wilson in 1967 and everything changed. Starting with aluminum and then switching over to today’s composites of graphite, carbon fiber and titanium, rackets have never been the same. In 1976 Prince came out with the Prince Classic, distinguished for its light weight, oversized head, bigger sweet spot, higher power and general playability, especially for beginners and intermediates. This essentially marked the end of the age of wooden rackets, as aluminum and high-tech composites took over the industry as the materials of choice. But hold on to those old wooden tennis racquets you have lying around the attic, they may be worth some money as an antique.

tennisQ. How do you review and rate the best tennis racket string?
A. With over 450 different types of string on the market, the average tennis player doesn’t know where or how to begin the search for the best tennis racket string. Choosing the wrong string type and inappropriate tension can make a $250 racket feel like a wooden club even to the most skilled of players. Here is a breakdown of the most common types of strings available:
Natural Gut: The undisputed champion of tennis strings. Gives both power and feel. Good choice for injury prevention and vibration dampening. Retains performance as it wears though is vulnerable to the ill effects of moisture.
Synthetic String with Solid Core: Offers a wide range of playability, power, or control. Its low cost is an attractive feature to players who go through lots of string.
Synthetic String with Multifilament Construction: Offers the most performance for the money. Aims to replicate natural gut at a much lower cost. Natural vibration dampening is a characteristic as it minimizes arm and wrist fatigue. Use these with textured surfaces for increased spin capability.
Polyester and Polyester Hybrid String: Excellent durability and power. Can be hard on the arm, however. Frequently used as the mains in a hybrid set-up.
