Ice Racing
Ice racing is a form of racing that uses cars, motorcycles, snowmobiles, all-terrain vehicles, or other motorized vehicles. Ice racing takes place on frozen lakes or rivers, or on groomed frozen lots. As cold weather is a requirement for natural ice, it is usually found at higher latitudes in Canada, the northern United States, and in northern Europe, although limited indoor events are held in warmer climates, typically on ice hockey rinks (motorcycles and ATVs only). Tracks in North America vary from 1/4 mile to several mile-long (~400 m to several kilometer-long) circuits. Track Tracks used for ice racing include ovals and road courses. Some tracks are dirt track racing tracks with the snow plowed off them. When there is no natural snow, an icy surface may be created by spraying the dirt surface with water when the temperature is below freezing. Artificial ice tracks (usually speed skating ovals) are used where it is not possible to construct natural ice tracks. Some track ...

Ice Speedway
Ice speedway is a developed form of motorcycle speedway racing, featuring racing on frozen surfaces. The sport uses bikes enhanced for the terrain. Participants can compete at international level. Outline The bikes race counterclockwise around oval tracks between 260 and 425 metres in length. The race structure and scoring are similar to that in speedway. History Ice speedway is an evolution of dirt speedway racing, which first started in 1923. Staten Lorenz of Michigan is generally credited with the invention of the sport, in 1975. The first ice speedway event was organized and promoted by a local motorcycle dealer in Huntsville, Alabama. The third ever event was hosted at the Kent State University hockey field house, which speedway rider Gary Densford was invited to attend by his friend Bob Hetrick. At this event, Hetrick finished first and Densford finished second. Densford went on to promote this new sport, forming the ICE (international Championship Events). Studs ...

Fédération Internationale De Motocyclisme
The Fédération Internationale de Motocyclisme (FIM; en, International Motorcycling Federation) is the global governing/sanctioning body of motorcycle racing. It represents 116 national motorcycle federations that are divided into six regional continental unions. There are seven motorcycle-racing disciplines that FIM covers, encompassing 82 world championships as well as hundreds of secondary championships: enduro, trial, circuit racing, motocross and supermoto, cross-country, e-bike, and track racing. FIM is also involved in many non-racing activities that promote the sport, its safety, and support relevant public policy. The FIM is also the first international sporting federation to publish an Environmental Code, in 1994. In 2007, a Commission for Women in Motorcycling was created by the FIM in order to promote the use of powered two-wheelers and the motorcycle sport among women.

Track Racing
Track racing is a form of motorcycle racing where teams or individuals race opponents around an unpaved oval track. There are differing variants, with each variant racing on a different surface type. The most common variant is Speedway which has many professional domestic and international competitions in a number of countries. Administered internationally by the Fédération Internationale de Motocyclisme (FIM), the sport became popular in the 1920s and remains so today. Nature of the sport Track racing involves between four and six, sometimes eight competitors riding around an oval track in a counter-clockwise direction over a set number of laps - usually four to six sometimes eight - with points being awarded to all but the last finisher on a sliding scale. These points are accumulated over a number of heats, with the winner being the team or individual who has scored the most overall. The machines used are customised motorcycles, these have no brakes and are fuelled with ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

4-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Traction (engineering)
Traction, or tractive force, is the force used to generate motion between a body and a tangential surface, through the use of dry friction, though the use of shear force of the surface is also commonly used. Traction can also refer to the ''maximum'' tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the ''coefficient of traction'' (similar to coefficient of friction). It is the force which makes an object move over the surface by overcoming all the resisting forces like friction, normal loads(load acting on the tiers in negative 'Z' axis), air resistance, rolling resistance, etc. Definitions Traction can be defined as: In vehicle dynamics, tractive force is closely related to the terms tractive effort and drawbar pull, though all three terms have different definitions. Coefficient of traction The ''coefficient of traction ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mudguard
A mudflap or mud guard is used in combination with the vehicle fender to protect the vehicle, passengers, other vehicles, and pedestrians from mud and other flying debris thrown into the air by the rotating tire. A mudflap is typically made from a flexible material such as rubber that is not easily damaged by contact with flying debris, the tire, or the road surface. On bicycles the mudflap is called a spoiler. It helps keep the rider(s) cleaner. Mudflaps can be large rectangular sheets suspended behind the tires, or may be small molded lips below the rear of the vehicle's wheel wells. Mudflaps can be aerodynamically engineered, utilizing shaping, louvers or vents to improve airflow and lower drag. While some flaps are plain, in the colour of rubber, many contain company logos, other art or sometimes advertisements. Another is the mudflap girl, a woman's silhouette. In the United States, there are mudflap regulations that vary from state to state. Aerodynamic Aerodynam ...

Screw
A screw and a bolt (see '' Differentiation between bolt and screw'' below) are similar types of fastener typically made of metal and characterized by a helical ridge, called a ''male thread'' (external thread). Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar ''female thread'' (internal thread) in a matching part. Screws are often self-threading (also known as self-tapping) where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevents pull-out. There are many screws for a variety of materials; materials commonly fastened by screws include wood, sheet metal, and plastic. Explanation A screw is a combination of simple machines: it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane (thread) also comes to a sharp edge around the outside, which acts as a wedge as it pushes into the fastened material, and th ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...
