When applying the principles of torque and horsepower:
A) Torque is calculated by multiplying force X distance
B) Torque is a force that does work with a twisting or turning motion
C) Horsepower is a measurement for the rate, or speed, at which work is done
D) All of the above

Question

Quizplus · Accepted Answer

A) Torque is calculated by multiplying force X distance. This is because torque is a twisting or turning force that is generated when a force is applied some distance from a pivot point (or axis of rotation).
B) Torque is a force that does work with a twisting or turning motion. This is the definition of torque - it is a force that causes rotational motion around an axis.
C) Horsepower is a measurement for the rate, or speed, at which work is done. This is partially correct - horsepower is a unit of power, which is a measure of how quickly work can be done. However, it is not specifically a measure of the rate at which work is done - it is a measure of the amount of work that can be done in a certain period of time (1 horsepower is equal to 550 foot-pounds per second). Nevertheless, this statement is correct in that horsepower is related to the rate at which work can be done.
