Racing Line
In motorsport, the racing line is the optimal path around a race course. In most cases, the line makes use of the entire width of the track to lengthen the radius of a turn: entering at the outside edge, touching the "apex"—a point on the inside edge—then exiting the turn by returning outside. Description Driving the racing line is a primary technique for minimizing the overall course time. As the optimal path around a race course, the racing line can often be glimpsed on the asphalt in the form of tire skid marks. A.J. Baime described its formation in the early laps of a race at Le Mans: Racing line optimization A primary goal of the racing driver is to determine the optimum line around a race track. This optimum line may vary depending on whether a driver wishes to achieve a minimum lap time during a qualifying session, conserve tires and fuel, or fend off a pass from another driver during a race. Race tracks are often broken down into separate elements such as standa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by ...

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] |
Racing Line Showing Earlier And Later Apex
In sport, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific goal. A race may be run continuously to finish or may be made up of several segments called heats, stages or legs. A heat is usually run over the same course at different times. A stage is a shorter section of a much longer course or a time trial. Early records of races are evident on pottery from ancient Greece, which depicted running men vying for first place. A chariot race is described in Homer's ''Iliad''. Etymology The word ''race'' comes from a Norse word. This Norse word arrived in France during the invading of Normandy and gave the word ''raz'' which means "swift water" in Brittany, as in a mill race; it can be found in "Pointe du Raz" (the most western point of France, in Brittany), and "''raz-de-marée''" (tsunami). The word rac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
24 Hours Of Le Mans
The 24 Hours of Le Mans (french: link=no, 24 Heures du Mans) is an endurance-focused sports car race held annually near the town of Le Mans, France. It is the world's oldest active endurance racing event. Unlike fixed-distance races whose winner is determined by minimum time, the 24 Hours of Le Mans is won by the car that covers the greatest distance in 24 hours. The cars on this track can go up to , and in prior events reaching before track modifications. Racing teams must balance the demands of speed with the cars' ability to run for 24 hours without mechanical failure. The race is organized by the Automobile Club de l'Ouest (ACO). It is held on the Circuit de la Sarthe, composed of closed public roads and dedicated sections of a racing track. The event represents one leg of the Triple Crown of Motorsport, with the other events being the Indianapolis 500 and the Monaco Grand Prix. The 24 Hours of Le Mans was frequently part of the World Sportscar Championship from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threshold Braking
Threshold braking or limit braking is a driving technique most commonly used in motor racing, but also practiced in road vehicles to slow a vehicle at the maximum rate using the brakes. The technique involves the driver controlling the brake pedal (or lever) pressure to maximize the braking force developed by the tires. The optimal amount of braking force is developed at the point when the wheel just begins to slip. Kinetic and static friction Braking beyond the slipping point causes the tire to slide and the frictional adhesion between the tire and driving surface is reduced. The aim of threshold braking is to keep the amount of tire slip at the optimal amount, the value that produces the maximum frictional, and thus braking force. When wheels are slipping significantly (kinetic friction), the amount of friction available for braking is typically substantially less than when the wheels are not slipping (static friction), thereby reducing the braking force and eliminating steering ...

Trail Braking
Trail braking is a driving and motorcycle riding technique where the brakes are used beyond the entrance to a turn (turn-in), and then gradually released (trailed off). Depending on a number of factors, the driver fully releases brake pressure at any point between turn-in and the apex of the turn. Motorcycling In applying this technique, motorcycle riders approach turns applying front brakes to reduce speed. As they enter the turn, they slowly ease off the brakes, gradually decreasing or trailing off the brakes as motorcycle lean increases. This is done for several reasons. First, it gives more traction because the downward force on the front tire is increased by load transfer. Second, as the brakes are applied and the weight shifts forward, the forks are compressed. The compression of the forks changes the motorcycle's steering geometry, decreasing stability in a way that makes the motorcycle more apt to lean and more quickly change direction. Third, decreasing speed decr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euler Spiral
An Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius). Euler spirals are also commonly referred to as spiros, clothoids, or Cornu spirals. Euler spirals have applications to diffraction computations. They are also widely used in railway and highway engineering to design transition curves between straight and curved sections of railway or roads. A similar application is also found in photonic integrated circuits. The principle of linear variation of the curvature of the transition curve between a tangent and a circular curve defines the geometry of the Euler spiral: *Its curvature begins with zero at the straight section (the tangent) and increases linearly with its curve length. *Where the Euler spiral meets the circular curve, its curvature becomes equal to that of the latter. Applications Track transition curve To travel along a circular path, an object needs to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving Techniques
Driving is the controlled operation and movement of a vehicle, including cars, motorcycles, trucks, buses, and bicycles. Permission to drive on public highways is granted based on a set of conditions being met and drivers are required to follow the established road and traffic laws in the location they are driving. The word driving, has etymology dating back to the 15th century and has developed as what driving has encompassed has changed from working animals in the 15th to automobiles in the 1800s. Driving skills have also developed since the 15th century with physical, mental and safety skills being required to drive. This evolution of the skills required to drive have been accompanied by the introduction of driving laws which relate to not only the driver but the driveability of a car. Etymology The origin of the term ''driver'', as recorded from the 15th century, refers to the occupation of driving working animals, especially pack horses or draft horses. The verb ' ' ...
