What is horsepower? Plain English guide to HP, BHP, kW, PS and CV Brake-horsepower is, in car terms, effectively the same as horsepower and simply indicates that an engine’s energy loss due to friction has been taken into account – though, because horsepower usually includes this anyway, they are effectively the same.

Torque, Horsepower and Speed? Best Answer: Torque is the twisting force that actually makes the vehicle or load move. Horsepower is an equivalency number to give an easily understandible rating and is what gives high speed power. http://www.wallaceracing.com/HP-TQ-RPM%2... RPM ( Revolutions Per Minute) is the speed the engine is running.

What does horse-power mean? Rating Newest Oldest. Best Answer: In physics terms, horsepower is used to measure the amount of work done. Work done is the mathematical expression of force x distance x time and is typically in ft/lbs/mins (Imperial) or Newton/Meters/mins (Metric). Horsepower was first coined by James Watt to measure the output of his new steam engines.

What is the meaning of torque and power in a car in layman terms? If you say a car has a particular torque at 3000 rpm and power at 4500rpm, what does it mean? As you may have already read, horsepower is just a function of torque and engine speed. First some definitions: Horsepower is the rating that describes how powerful an engine is. Torque can be described as how flexible or how much force can be expressed in a given gear.

What is the meaning of BHP and torque in bikes or cars? Torque is how strong your engine is and Horsepower is a measure of how fast it can use that power. That is why a Diesel engine with 400Nm of Torque cannot out-accellerate a petrol car with 400Nm of Torque. Horsepower is calculated by multiplying the amount of torque by the RPM of the engine (and dividing by 5,252.

- In the past, before the widespread adoption of SI units, the work that engines were capable of doing was compared with the work that horses could do – hence the term ‘horsepower’. Various people came up with various equivalencies, but the modern agreed definition is that 1 horsepower is 746 joules per second or 746 watts. A metric horsepower (symbol often PS from the German abbreviation), approximately equal to 735.5 watts. Strength political horsepower.
