what is the difference between torque of the car and its orse power?

Question

car horse power and its torque

Answer 1

Torque is the pure rotational force that an engine can put out. It's what breaks the tires loose at the stop light.

Horsepower measures how well the engine can continue to produce torque as speed increases. An engine that can maintain a higher torque at speed will have greater horsepower than one that peaks out sooner.

Horsepower gets you top speed. Torque gets you off the line quickly, and helps pull heavy loads.

Answer 2

Horsepower is how fast you hit the wall. Torque is how far you move that wall... Torque The amount of force needed to turn a bolt or screw is the torque. There are many different units of measurement for this, but the most common is foot-pounds. A simple torque calculation is the amount of power (pounds) needed to turn a 1-foot-long wrench to tighten a bolt. So as the length of the wrench changes the amount of pounds needed to turn it will change. Normally the longer the wrench, the less amount of pounds needed. Horsepower The unit horsepower was actually created by James Watt. This was also the gentleman that discovered the watt found in the 60-watt light bulb. In his time animals, mainly horses, were used for work. He calculated how much work, in foot-pounds, a horse could achieve in a minute. This is really very arbitrary, as all horses will do a different amount of work. However, it has become the standard for engines and other machines. Thus, 1hp equates to a horse moving a 330-pound load 100 feet in a minute. So 1 hp = 33,000 foot-pounds

Answer 3

power is the rate at which torque is delivered. P = T*omega, where T is the torque of the engine crankshaft and omega is the rotational speed in radians per second. There are 2*pi radians per revolution of the crankshaft.

Answer 4

Put simply, horsepower is just torque with a time factor added.

Answer 5

Work = Torque (ft. lb.) x angle thru which the torque acts, in radians

Work = Torque (ft. lb.) x (2 x Pi x Number of Revolutions)

HorsePower = Work/time = ft-lb/minute

1 horsepower = 33,000 ft. lb./min.

HP=Torque(ft.lb.)x(2xPixNumber of Revs)/(minutes x 33,000)
