Gocart Sulfate Optical Thickness
A go-kart, also written as go-cart (often referred to as simply a kart), is a type of small sports car, close wheeled car, open-wheel car or quadracycle. Go-karts come in all shapes and forms, from non-motorised models to high-performance Kart racing, racing karts. Karting is a type of racing in which a compact four-wheel unit called a go-kart is used. Art Ingels created the first go-kart in Los Angeles in 1956. Etymology The exact origin of the term is unclear. One of the first appearances of the term is an 1885 painting by the Scottish artist Hugh Cameron (artist), Hugh Cameron's "The Go-Cart". It is also unclear why the ''C'' was later changed to a ''K''. In the film ''The Ivory-Handled Gun'' (1935), the crippled father of Buck Jones refers to his wheelchair as a "go cart". Charles Dickens also used ''go-cart'' in ''Master Humphrey's Clock and Other Stories'' when talking of his travel to Italy. In Genoa, he talks about "a man without legs, on a little go-cart".

Bicycle Pedals
The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or shoe and the crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels. A pedal usually consists of a spindle that threads into the end of the crank, and a body on which the foot rest is attached, that is free to rotate on bearings with respect to the spindle. Pedals were initially attached to cranks connecting directly to the driven (usually front) wheel. The safety bicycle, as it is known today, came into being when the pedals were attached to a crank driving a sprocket that transmitted power to the driven wheel by means of a roller chain. Types Just as bicycles come in many varieties, there are different types of pedals to support different types of cycling. Flat and platform Traditionally, platform pedals were pedals with a relatively large flat area for the foot to rest on, in contrast to ...

Model Car
A model car, or toy car, is a Physical model, miniature representation of an automobile. Other miniature motor vehicles, such as trucks, buses, or even All-terrain vehicle, ATVs, etc. are often included in this general category. Because many miniature vehicles were originally aimed at children as Toy, playthings, there is no precise difference between a model car and a toy car, yet the word 'model' implies either assembly required or the accurate rendering of an actual vehicle at smaller scale. The kit building hobby became popular through the 1950s, while the collecting of miniatures by adults started to gain momentum around 1970. Precision-detailed miniatures made specifically for adults are a significant part of the market since the mid-1980s. The scope of the vehicles involved in the hobby, according to Louis Heilbroner Hertz author of ''The Complete Book of Building and Collecting Model Automobiles'', encompasses "ordinary or stock automobiles, racing cars ([...]), buses, t ...

Kart Circuits
A kart circuit is a race track designed for kart racing or other forms of short-length motor racing, such as small-scale motorcycle racing, pocketbike racing, or radio-controlled model racing. There are several types of kart circuit, depending on the type of use desired. Unlike regular race tracks intended for auto racing or other forms of motorsports, kart circuits are usually much shorter in length, narrower, and contains numerous turns or corners. Circuit types Short circuit A short circuit is defined as being an outdoor circuit of less than 1,500 meters in length . The average length for a serious racing track for karts is around 1,100 - 1,200 meters, 7 to 9 meters in width. Normally custom-built for karting, they resemble road courses, with left and right turns. They generally allow sprint racing for both gearbox and non-gearbox karts. Temporary circuits can be set in city streets or large parking lots for special events. This is the case for the Junior Monaco Kart Cup ...

Hydrogen Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Grove in 1838. The first commercial use of fuel cells came almost a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for satellites and space capsules. Since then, fuel cells have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollution
Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants Human impact on the environment, have a human source, such as manufacturing, Extractivism, extractive industries, poor waste management, transportation or Agricultural pollution, agriculture. Pollution is often classed as point source pollution, point source (coming from a highly concentrated specific site, such as a factory, Environmental effects of mining, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff). Many sources of po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Go-kart
An electric go-kart is a type of go-kart powered by Electric motor, electric motors and Battery (electricity), batteries or supercapacitors, as opposed to a traditional petrol engine. As of 2022, electric go-karts are mostly used for rental go-karts for recreational usage. For serious kart racing, traditional 2-stroke petrol engines are mostly used, but development of high-performance electric karts is taking place and races are already being held with electric go-karts. In 2018, the Fédération Internationale de l'Automobile, FIA and the International Olympic Committee joined forces to introduce electric karting as the first motorsport in the Youth Olympic Games, Youth Olympics, with the aim of having the first championship at the 2024 Summer Olympics in Paris. History Since 2006, a race for students called e-Kart has been organized in France, which brings together manufacturers, schools and academic institutions in areas such as Electrical engineering, electrical and mecha ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or Scavenging (automotive), scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringe ...

Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an eccentric (mechanism), eccentric Pistonless rotary engine, rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor spins inside a figure-eight-like epitrochoidal housing around a fixed gear. The midpoint of the rotor moves in a circle around the output shaft, rotating the shaft via a Cam (mechanism), cam. In its basic gasoline-fuelled form, the Wankel engine has lower thermal efficiency and higher exhaust emissions relative to the Four-stroke engine, four-stroke reciprocating engine. This thermal inefficiency has restricted the Wankel engine to limited use since its introduction in the 1960s. However, many disadvantages have mainly been overcome ...
