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 pre-determined 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 greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' 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 Arabs developed the digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorsport
Motorsport, motorsports or motor sport is a global term used to encompass the group of competitive sporting events which primarily involve the use of motorized vehicles. The terminology can also be used to describe forms of competition of two-wheeled motorised vehicles under the banner of motorcycle racing, and includes off-road racing such as motocross. Four- (or more) wheeled motorsport competition is globally governed by the Fédération Internationale de l'Automobile (FIA); and the Fédération Internationale de Motocyclisme (FIM) governs two-wheeled competition. Likewise, the Union Internationale Motonautique (UIM) governs powerboat racing while the Fédération Aéronautique Internationale (FAI) governs air sports, including aeroplane racing. All vehicles that participate in motorsports must adhere to the regulations that are set out by the respective global governing body. History In 1894, a French newspaper organised a race from Paris to Rouen and back, star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standing Start
A standing start is a type of start in auto racing events, in which cars are stationary when the race begins (different to the rolling start, where cars are paced). 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 Formula 2 notably), Touring Cars (most notably British and 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 formation lap takes place, giving time for team personnel to get clear of the starting grid and back into the pit boxes. Once the formation lap is over, all cars position themselves in the order that they qualified, and the Medical Car positions itself behind the pack. Once the Medical Car is in position, a light system consisting of five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-way Radio
A two-way radio is a radio that can both transmit and receive radio waves (a transceiver), unlike a broadcast receiver which only receives content. It is an audio (sound) transceiver, a transmitter and receiver in one unit, used for bidirectional person-to-person voice communication with other users with similar radios. Two-way radios are available in stationary (base station), mobile (installed in vehicles), and hand-held portable models. Hand-held two-way radios are often called walkie-talkies, handie-talkies or hand-helds. Two-way radios are used by groups of geographically separated people who need to keep in continuous voice communication, such as aircraft pilots and air traffic controllers, ship captains and harbormasters, emergency services personnel like firefighters, police officers, and ambulance paramedics, taxi and delivery services, soldiers and military units, fast food and warehouse employees, and radio amateurs. Two-way radio systems may use a single radio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stock Car Racing
Stock car racing is a form of automobile racing run on oval tracks and road courses measuring approximately . It originally used production-model cars, hence the name "stock car", but is now run using cars specifically built for racing. It originated in the southern United States; the world's largest governing body is the American NASCAR. Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Australia, Canada, New Zealand, Mexico, Brazil and the United Kingdom also have forms of stock car racing. 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 860–900 hp from their naturally aspirated V8 engines. In October 2007 American race car driver Russ Wicks set a speed record for stock cars in a 2007-season Dodge Charger buil ...

Sports Car Racing
Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built prototypes or grand tourers based on road-going models. Broadly speaking, sports car racing is one of the main types of circuit auto racing, alongside open-wheel single-seater racing (such as Formula One), touring car racing (such as the British Touring Car Championship, which is based on 'saloon cars' as opposed to the 'exotics' seen in sports cars) and stock car racing (such as NASCAR). Sports car races are often, though not always, endurance races that are run over relatively large distances, and there is usually a larger emphasis placed on the reliability and efficiency of the car as opposed to outright speed of the driver. The FIA World Endurance Championship is an example of a sports car racing series. A type of hybrid between the purism of open-wheelers and the familiarity of touring car racing, this style is often associa ...

Touring Car Racing
Touring car racing is a motorsport road racing competition with heavily modified road-going 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 or sports car races, their similarity both to one another and to fans' own vehicles makes for entertaining, 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 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 of a touring car Touring car racing started in the mid twentieth century as a long-format style ... [...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, so 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 ...

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. 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. History Early stock car racing In the 1920s and 1930s, Daytona Beach supplanted France and Belgium as the preferred location for world land speed records. After a historic race between Ransom Olds and Alexander Winton in 1903, 15 records were set on what became the Daytona Beach Road Course between 1905 and 1935. Daytona Beach had become synonymous with fast cars in 1936. Drivers raced on a course, consisting of a stretch of beach as one straightaway, and a narrow blacktop beachfront highway, ...

Indianapolis 500
The Indianapolis 500, formally known as the Indianapolis 500-Mile Race, and commonly called the Indy 500, is an annual automobile race held at Indianapolis Motor Speedway (IMS) 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 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 typically shares a date. The official attendance is not disclosed by Speedway management, but the permanent seating capacity is upwards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
