Handbrake Turn
The handbrake turn (also known as a bootleg or bootlegger's turn) is a driving technique used to deliberately slide a car sideways, either for the purpose of quickly negotiating a very tight bend, or for turning around well within the vehicle's own turning diameter. Technique The driver starts by using steering input to transfer weight to the outside tires; the Hand brake, handbrake is then used to lock the rear wheels, thus upsetting the adhesion between the tires and the road surface. With practice, the car can be placed accurately by releasing the handbrake and accelerating the vehicle. The technique is used in some forms of auto racing, motorsport, for example rallying, autotesting, Drifting (motorsport), drifting and motorkhana. Many sports cars, especially UK makes such as MG and Triumph, as late as the early 1970s were offered with a fly-off handbrake option for competition purposes—the button on the end of the lever has to be pressed before the brake will lock on, whi ...

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 ...

Bootleg Turn
A bootleg turn is a driving maneuver intended to reverse the direction of travel of a forward-moving automobile by 180 degrees in a minimum amount of time while staying within the width of a two-lane road. This maneuver is also known as a smuggler's turn, powerslide, or simply bootlegger. Technique The driver performs the turn by putting the vehicle quickly into a lower gear, usually the gear ratio, second, and quickly turning the wheel in the direction of the opposite lane. If performed correctly, it will cause the vehicle to enter a controlled skid, enter the opposite lane, and turn completely around. In a perfect bootleg turn, the car will be at a complete stop at the end of the maneuver and ready to accelerate and depart in the opposite direction. It is easier to initiate this with some cars by applying a flick of the steering wheel the wrong way initially, before turning it in the direction the driver wants to go. This maneuver (known in racing as a Scandinavian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Left-foot Braking
Left-foot braking is the technique of using the left foot to operate the brake pedal in an automobile, leaving the right foot dedicated to the throttle pedal. It contrasts with the practice of using the left foot to operate the clutch pedal, leaving the right foot to share the duties of controlling both brake and gas pedals. At its most basic purpose, left-foot braking is used to decrease the time spent moving the right foot between the brake and throttle pedals, and can also be used to control load transfer. It is most commonly used in auto racing, where simultaneous gas and brake keeps revs up. In turbocharged vehicles, left-foot braking keeps pressure up and reduces turbo lag. Racing and rallying Karts, many open-wheelers, and cars that are equipped with automatic transmissions, or semi-automatic transmissions with paddle-shifters (as used in motorsports such as Formula One) have no foot-operated clutch, and allow, or sometimes even require the driver to use their left foo ...

Vehicle Rollover
A rollover or overturn is a type of vehicle crash in which a vehicle tips over onto its side or roof. Rollovers have a higher fatality rate than other types of vehicle collisions. Dynamics Vehicle rollovers are divided into two categories: tripped and untripped. Tripped rollovers are caused by forces from an external object, such as a curb or a collision with another vehicle. Untripped rollovers are the result of steering input, speed, and friction with the ground. Trailers that are not roll-coupled (i.e. those that use a trailer coupling rather than a fifth wheel) are more prone to rolling as they do not have the tractor unit or prime mover for additional stability. Untripped rollovers Untripped rollovers occur when cornering forces destabilize the vehicle. As a vehicle rounds a corner, three forces act on it: tire forces (the centripetal force), inertial effects (the centrifugal force), and gravity. The cornering forces from the tire push the vehicle towards the center of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-point Turn
The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn, and there are no driveways or sideroads that are conducive to a two-point turn. Three-point turns are dangerous because they make the driver vulnerable to oncoming traffic for an extended period of time. For this reason, they are generally recommended to be used only as a last resort. This manoeuvre is a common requirement in driving tests. Process The basic manoeuvre consists of driving across the road turning towards the offside kerb, reversing across the road to the original nearside kerb while turning, and driving forward towards the original offside kerb, now the nearside. In a narrow road or with a longer vehicle, more than three legs may be required to achieve a full 180 degree rotation. Naming ' ...

Boy Racer
Boy racer is a term given to a young person who drives in a fast and aggressive manner; it has become a broader term (often pejorative) for participants in modern custom car culture who tune and modify cars with street racing-style aftermarket cosmetic and performance parts such as body kits, audio systems and exhausts. The culture encompasses a broad range of car types including sport compacts and economy cars typical of the import scene, this is in contrast with the hot rod culture of previous generations. Some car enthusiasts and modifiers feel the term labels them as deviant and anti-social and are keen to distance themselves from the term. Boy racer is a term mostly but not exclusively associated with the UK, in Australia and New Zealand hoon is sometimes preferred. In the US, "Rice boy" or "Ricer" is a derogatory term for the driver or builder of an imported hot rod, or someone who modifies their car in a cheap way to imitate the look of a higher performance vehic ...

Parallel parking usually requires initially driving slightly past the parking space, parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space. Subsequent position adjustment may require the use of forward and reverse gears. Techniques Parallel parking is considered to be one of the most stressful and difficult skills for new drivers to learn. While parallel parking is a required part of most driving tests, several states in the US have dropped it as a requirement. Parallel parking enables the driver to park a vehicle in a smaller space than would be true of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stunt
A stunt is an unusual, difficult, dramatic physical feat that may require a special skill, performed for artistic purposes usually for a public audience, as on television or in theaters or cinema. Stunts are a feature of many action films. Before computer-generated imagery special effects, these depictions were limited to the use of models, false perspective and other in-camera effects, unless the creator could find someone willing to carry them out, even such dangerous acts as jumping from car to car in motion or hanging from the edge of a skyscraper: the stunt performer or stunt double. Types of stunt effects Practical effects One of the most-frequently used practical stunts is stage combat. Although contact is normally avoided, many elements of stage combat, such as sword fighting, martial arts, and acrobatics required contact between performers in order to facilitate the creation of a particular effect, such as noise or physical interaction. Stunt performances are highly c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centripetal Force
Centripetal force (from Latin ''centrum'', "center" and ''petere'', "to seek") is the force that makes a body follow a curved trajectory, path. The direction of the centripetal force is always orthogonality, orthogonal to the motion of the body and towards the fixed point of the instantaneous osculating circle, center of curvature of the path. Isaac Newton coined the term, describing it as "a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre". In Newtonian mechanics, gravity provides the centripetal force causing astronomical orbits. One common example involving centripetal force is the case in which a body moves with uniform speed along a circular path. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. The mathematical description was derived in 1659 by the Dutch physicist Christiaan Huygens. Formula From the kinematics of curved motion it is known ...

Turning Diameter
The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter) of available space required for that vehicle to make a semi-circular U-turn without skidding. The Oxford English Dictionary describes turning circle as "the smallest circle within which a ship, motor vehicle, etc., can be turned round completely". The term thus refers to a theoretical minimal circle in which for example an aeroplane, a ground vehicle or a watercraft can be turned around. The terms (''radius'', ''diameter'', or ''circle'') can have different meanings; refer to the section. Definition On wheeled vehicles with the common type of front wheel steering (i.e. one, two or even four wheels at the front capable of steering), the vehicle's ''turning diameter'' measures the minimum space needed to turn the vehicle around while the steering is set to its maximum displacement from the central 'straight ahead' position - i.e. ei ...
