Horsepower. One imperial horsepower lifts 550 pounds (250 kg) by 1 foot (30 cm) in 1 second. Horsepower ( hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
One metric horsepower is needed to lift 75 kilograms by 1 metre in 1 second. Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity.
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
Between 1995 and 2000, cars using this 3.0 L engine formula, imposed by the FIA, produced a constant power range (depending on engine type and tuning), varying between 600 hp and 815 hp. Most Formula One cars during the 1997 season comfortably produced a consistent power output of between 665–760 hp (495.9–566.7 kW), depending on whether a ...
In physics and mechanics, torque is the rotational analogue of linear force. [ 1] It is also referred to as the moment of force (also abbreviated to moment ). The symbol for torque is typically , the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.
A modern-day Ferrari Formula One car being tested by Fernando Alonso at Jerez. The car is the Ferrari F10. In recent years, most Formula One teams have tried to emulate Ferrari's 'narrow waist' design, where the rear of the car is made as narrow and low as possible. This reduces drag and maximises the amount of air available to the rear wing.
Tax horsepower. The tax horsepower or taxable horsepower was an early system by which taxation rates for automobiles were reckoned in some European countries such as Britain, Belgium, Germany, France and Italy; some US states like Illinois charged license plate purchase and renewal fees for passenger automobiles based on taxable horsepower.
Formula Three, also called Formula 3, abbreviated as F3, is a third-tier class of open-wheel formula racing. The various championships held in Europe, Australia, South America and Asia form an important step for many prospective Formula One drivers.
