A Simpler Explanation Of The Measurement Of ONE HORSE POWER
One horsepower equals 550 foot pounds (pound feet) per second. In high school, in physics class, I generated 1 horsepower by running up a flight of stairs. :) Housted
Forum Discussion
Whenever there is discussion regarding an engine's horsepower engine torque is likely to come up. People often bring up definitions of torque and horsepower and stress that torque is a measure of force where as horsepower is a measure of power or rate at which work is done. The definitions are of some value but the thing that is often overlooked is the fact that power and torque ratings are peak values and are given at a specified rpm. Neither value on its own gives a clear picture of an engine's usable power but wen considered together the two values along with their specified rpm give a clear picture of an engine's power curve. Torque is meaningless without stating an rpm and when the rpm is stated along with the torque value it is an indication of engine power at that rpm.
