Rollout (drag Racing)
Rollout or rollout allowance in North-American drag racing is the difference between actual acceleration time and measured acceleration time. For the published 0 to 60 mph acceleration time in North America, a rolling start is used, beginning after the initial standing start position. The method approximates the behaviour of dragstrip measurement equipment for 1/4 mile racing, which was historically limited to only recording after the vehicle had passed over a start line. This leads to a 0.2–0.3-second apparent difference, with larger wheel sizes giving a larger exaggeration in timing. History Historically acceleration measurement took place using dragstrip equipment placed over a measured distance, with a light gate at the start and end. These light gates measured the point in time at which a vehicle passed the measurement point, rather than the point at which movement (acceleration) first occurred leading to a slightly faster apparent time.

Drag Racing
Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly , with a shorter, distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s. The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing and as a regulated motorsport. History Drag racing started in the 1940s. World War II veterans were prominently involved, and some early drag races were done at decommissioned aircraft b ...

0 To 60 Mph
The time it takes a vehicle to accelerate from 0 to 60 miles per hour (0 to 97 km/h or 0 to 27 m/s), often said just "zero to sixty", is a commonly used performance measure for automotive acceleration in the United States and the United Kingdom. In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used. Present performance cars are capable of going from 0 to 60 mph in under 5 seconds, while exotic cars can do 0 to 60 mph in between 2 and 3 seconds, whereas motorcycles have been able to achieve these figures with sub-500 cc since the 1990s. The fastest automobile in 2015 was the Porsche 918 Spyder, which is a hybrid vehicle taking 2.2 seconds to accelerate from 0 to 60 mph. In June 2021, the Tesla Model S was measured to accelerate from 0 to 60 mph in 1.98 seconds, not including first foot of rollout. Methods Measuring the 0 to 60 mph speed of vehicles is usually done in a closed setting such as a race car track or closed lo ...

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. In international-le ... [...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] |
Dragstrip
A dragstrip is a facility for conducting automobile and motorcycle acceleration events such as drag racing. Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction. Features A dragstrip is a straight, purpose-built racetrack, typically an eighth, ten feet longer than three-sixteenths, or a quarter of a mile long (660/1,000/1320 feet, 201/304.8/402 m), with an additional ''shutdown area'' to allow vehicles room to stop after crossing the finish line. Common features also include a 'water box' where vehicles and motorcycles start their burnouts for tire clean-up and also to heat up their tires to improve traction. There is a set of lights known as a 'Christma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Size
The wheel size for a motor vehicle or similar wheel has a number of parameters. Units The millimetre is most commonly used to specify dimensions in modern production, but marketing of wheel sizes towards customers is still sometimes done with traditional systems. For example, wheels for road bicycles are often referred to as 700C, when they actually measure 622 mm. Wheel diameters and widths for cars are stated in inches, while car tire bead diameters are stated in inches and widths are in millimetres. Wheel size 200px, Wheels with Asanti rims on a police Hummer H2 car The ''wheel size'' is the size designation of a wheel given by its diameter, width, and offset. The diameter of the wheel is the diameter of the cylindrical surface on which the tire bead rides. The width is the inside distance between the bead seat faces. The offset is the distance from the wheel's true centerline (half the width) to the wheel's mounting surface. Offset is covered in more detail below. A t ...

Exaggeration
Exaggeration is the representation of something as more extreme or dramatic than it really is. Exaggeration may occur intentionally or unintentionally. Exaggeration can be a rhetorical device or figure of speech. It may be used to evoke strong feelings or to create a strong impression. Amplifying achievements, obstacles and problems to seek attention is an everyday occurrence Inflating the difficulty of achieving a goal after attaining it, can be used to bolster self-esteem. In the arts, exaggerations are used to create emphasis or effect. As a literary device, exaggerations is often used in poetry, and is frequently encountered in casual speech. Many times the usages of hyperbole describes something as better or worse than it really is. An example of hyperbole is: "The bag weighed a ton." Hyperbole makes the point that the bag was very heavy, though it probably does not weigh a ton. Exaggerating is also a type of deception,Guerrero, L., Anderson, P., Afifi, W. (2007). Cl ...

Distance
Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). Since spatial cognition is a rich source of conceptual metaphors in human thought, the term is also frequently used metaphorically to mean a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between strings of text) or a degree of separation (as exemplified by distance between people in a social network). Most such notions of distance, both physical and metaphorical, are formalized in mathematics using the notion of a metric space. In the social sciences, distance can refer to a qualitative measurement of separation, such as social distance or psychological distance. Distances in physics and geometry The distance between physica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
