Rolling Start
A rolling start is one of two modes of initiating or restarting an auto race; the other mode is the standing start. In a rolling start, the cars are ordered on the track and are led on a certain number of laps (parade or caution laps) at a predetermined safe speed by the safety car. Procedure When race conditions are ready, the safety car will leave the track, and the race marshal will show the green flag, indicating that the field is allowed to accelerate. The safety car typically leaves the track some distance before the finish line, and a few seconds may elapse between the safety car's departure and the showing of the green flag. Cars must wait for the green flag to accelerate to race speeds. In the past, drivers would need to look for the flag, but in modern times this information is typically communicated to drivers via two-way radio, or at the proper acceleration zone, marked by a line or cone, determined at the pre-race drivers and mechanics briefing.

2007 Indianapolis 500 - Starting Field Formation Before Start
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has symbolic associations in religion, mythology, superstition and philosophy. The seven classical planets resulted in seven being the number of days in a week. 7 is often considered lucky in Western culture and is often seen as highly symbolic. Evolution of the Arabic digit For early Brahmi numerals, 7 was written more or less in one stroke as a curve that looks like an uppercase vertically inverted (ᒉ). The western Arab peoples' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arab peoples developed the digit from a form that looked something like 6 to one that looked like an uppercase V. Both modern Arab forms influenced the European form, a two-stroke form consisting of a ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorsport
Motorsport or motor sport are sporting events, competitions and related activities that primarily involve the use of Car, automobiles, motorcycles, motorboats and Aircraft, powered aircraft. For each of these vehicle types, the more specific terms ''automobile sport'', ''motorcycle sport'', Motorboat#Racing, ''power boating'' and ''air sports'' may be used commonly, or officially by organisers and governing bodies. Different manifestations of motorsport with their own objectives and specific rules are called disciplines. Examples include Race track, circuit racing, rallying and Classic trial, trials. Governing bodies, also called sanctioning bodies, often have general rules for each discipline, but allow supplementary rules to define the character of a particular competition, series or championship. Groups of these are often categorised informally, such as by vehicle type, surface type or propulsion method. Examples of categories within a discipline are formula racing, stock car r ...

Standing Start
A standing start is a type of start in automobile, auto auto racing, racing events, in which cars are stationary when the race begins (different to the rolling start, where cars are paced). Some categories of land speed record also require a standing start, although the absolute land speed record uses a flying start, where the vehicle has reached its top speed by the starting point of the timer. Procedure In a standing start, cars are completely still but with their engines running when the signal is given to start the race. This is often preceded by a set number of lights. Standing starts are common in many motorsports, including most single-seater (Formula 1 and FIA Formula 2 Championship, Formula 2 notably), Touring Cars (most notably British Touring Car Championship, British and World Touring Car Championship, World Touring Cars), drag racing, the Supercars Championship, kart racing, and many types of short-course off-road racing. In a typical standing start, the Parade lap, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Car
In motorsport, a safety car, or a pace car, is a car that limits the speed of competing cars or motorcycles on a racetrack in the case of a ''caution period,'' such as an obstruction on the track or bad weather. The safety car aims to enable the clearance of any obstruction under safer conditions, especially for Motorsport marshal, marshals and/or awaiting more favourable track conditions weather-wise. By following the safety car, the competitors' tyres remain as close as possible to operating temperature while their engines do not overheat. A safety car is also preferred over stopping the race (Red flag (racing), red flag) and restarting, as the latter takes longer. During a caution period, the safety car (which is typically an appropriately modified high-performance production car) enters the track ahead of the leader. Depending on the regulations in effect, competitors are not normally allowed to pass the safety car or other competitors during a caution period, and the safety ...

Two-way Radio
A two-way radio is a radio transceiver (a radio that can both transmit and receive radio waves), which is used for bidirectional person-to-person voice communication with other users with similar radios, in contrast to a broadcast receiver, which only receives transmissions. Two-way radios usually use a half-duplex communication channel, which permits two-way communication, albeit with the limitation that only one user can transmit at a time. (This is in contrast to simplex communication, in which transmission can only be sent in one direction, and full-duplex, which allows transmission in both directions simultaneously.) This requires users in a group to take turns talking. The radio is normally in receive mode so the user can hear all other transmissions on the channel. When the user wants to talk, they press a " push-to-talk" button, which turns off the receiver and turns on the transmitter; when the button is released, the receiver is activated again. Multiple channels are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stock Car Racing
Stock car racing is a form of Auto racing, automobile racing run on oval track racing, oval tracks and road courses. It originally used Production vehicle, production-model cars, hence the name "stock car", but is now run using cars specifically built for racing. It originated in the Culture of the Southern United States, southern United States and later spread to Japan; its largest governing body is NASCAR. Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Canada, Mexico, Brazil, Argentina and Chile also have forms of stock car racing in the Americas. Other countries, such as Australia, New Zealand and the United Kingdom, have forms of stock car racing worldwide as well. Top-level races typically range between in length. Top-level stock cars exceed at speedway tracks and on superspeedway tracks such as Daytona International Speedway and Talladega Superspeedway. Contemporary NASCAR-spec top-level cars produce maximum power outputs of 860� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Car Racing
Sports car racing is a form of motorsport road racing that uses sports cars with two seats and enclosed wheels. They may be either purpose-built Sports prototype, sports prototypes, which are the highest level in sports car racing; or grand tourers (GT cars) based on road-going models and therefore, in general, not as fast as sports prototypes. Sports car races are often Endurance racing (motorsport), endurance races run over particularly long distances or large amounts of time, emphazing on reliability and efficiency of the car and its drivers more than outright car performance or driver skills. The FIA World Endurance Championship and IMSA SportsCar Championship are some of the best-known sports car racing series. Sports car racing is one of the main types of circuit auto racing, alongside open-wheel racing (such as Formula One), touring car racing (such as British Touring Car Championship, BTCC, which is based on 'saloon cars' as opposed to the 'exotics' seen in sports cars) ...

Touring Car Racing
Touring car racing is a motorsport road racing competition that uses race-prepared touring cars. It has both similarities to and significant differences from stock car racing, which is popular in the United States. While the cars do not move as fast as those in Formula racing, formula or sports car racing, sports car races, their similarity both to one another and to fans' own vehicles makes for well-supported racing. The lesser use of aerodynamics means following cars have a much easier time passing than in open-wheel racing, and the more substantial bodies of the cars makes the subtle bumping and nudging for overtaking much more acceptable as part of racing. As well as short ''sprint'' races, many touring car series include one or more Endurance racing (motorsport), endurance races, which last anything from 3 to 24 hours and are a test of reliability and pit crews as much as car, driver speed, and consistency. Characteristics Touring car racing started in the mid twentiet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine in wh ...

NASCAR
The National Association for Stock Car Auto Racing, LLC (NASCAR) is an American auto racing sanctioning and operating company that is best known for stock car racing. It is considered to be one of the top ranked motorsports organizations in the world and is one of the largest spectator sports leagues in America. The privately owned company was founded by Bill France Sr. in 1948, and his son, Jim France, has been the CEO since August 2018. The company is headquartered in Daytona Beach, Florida. Each year, NASCAR sanctions over 1,500 races at over 100 tracks in 48 US states, as well as in Canada, Mexico, Brazil and Europe. NASCAR, and stock car racing as a whole, traces its roots back to moonshine runners during Prohibition in the United States, Prohibition, who grew to compete against each other in a show of pride. This happened notably in North Carolina. In 1935, Bill France Sr. established races in Daytona Beach, with the hope that people would come to watch races and that r ...

Indianapolis 500
The Indianapolis 500, formally known as the Indianapolis 500-Mile Race, and commonly shortened to Indy 500, is an annual automobile race held at the Indianapolis Motor Speedway in Speedway, Indiana, United States, an enclave suburb of Indianapolis. The event is traditionally held over Memorial Day weekend, usually the last weekend of May. It is contested as part of the IndyCar Series, the top level of American open-wheel car racing, a formula colloquially known as "Indy car racing". The track itself is nicknamed the "Brickyard", as the racing surface was first paved in brick in the fall of 1909. One yard of brick remains exposed at the start/finish line. The event, billed as ''The Greatest Spectacle in Racing'', is considered part of the Triple Crown of Motorsport along with the 24 Hours of Le Mans and the Monaco Grand Prix, with which it has frequently shared a date. The inaugural race was held in 1911 and was won by Ray Harroun. The event celebrated its 100th anniversary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
