The FIA estimate the speed increase to be between 10–12 km/h (6.2–7.5 mph) by the end of the activation zone, [8] while others, such as technical staff at racecar-engineering.com, [9] cite a much lower figure of 4–5 km/h (2.5–3.1 mph). When the DRS is deactivated or closed, it increases downforce, giving better cornering.
Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. [1] The "formula" in the name refers to a set of rules to which all participants and cars must conform. [2] Each year, the F1 World Championship season is held.
The requirement for power input to an ideal mechanism to equal power output provides a simple way to compute mechanical advantage from the input-output speed ratio of the system. The power input to a gear train with a torque T A applied to the drive pulley which rotates at an angular velocity of ω A is P=T A ω A.
Underdrive pulleys increase engine output by reducing the draw of the engine's accessories by slowing them down and reducing the horsepower (HP) they use. Horsepower gains from underdrive pulleys can vary by vehicle, engine, number of accessories and the amount of underdrive (improvements of up to 5–15 HP at the wheels have been seen).
Simple CVTs combining a centrifugal drive pulley with a spring-loaded driven pulley often use belt tension to effect the conforming adjustments in the driven pulley. [3] The V-belt needs to be very stiff in the pulley's axial direction to make only short radial movements while sliding in and out of the pulleys.
Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft.
The rules regarding the awarding of points were reviewed by FIA, teams and Formula One following criticism after the 2021 Belgian Grand Prix, during which the race was red flagged on lap 3 after two laps behind the safety car, with no laps having been completed under green flag conditions at racing speed, before the race was abandoned ...
The Mercedes-Benz W196 (sometimes written as the Mercedes-Benz W 196 R [1]) was a Formula One racing car produced by Mercedes-Benz for the 1954 and 1955 F1 seasons. Successor to the W194, in the hands of Juan Manuel Fangio and Stirling Moss it won 9 of 12 races entered and captured the only two world championships in which it competed.
