How is torque commonly measured in mechanics?

Torque is a measure of rotational force, and it indicates how much force is applied at a certain distance from the pivot point or axis of rotation. The common unit for measuring torque in mechanics is foot-pounds, which represents the amount of torque created when a force of one pound is applied at a distance of one foot from the pivot point. This unit effectively communicates both the strength of the force and the distance from the pivot at which it acts, making it a practical and widely understood measurement in various applications involving rotational motion.

In contrast, horsepower, while it relates to power and performance, does not directly measure torque. Horsepower ratings and total horsepower are both indicators of a system's power output rather than rotational force. Pressure units are typically used to measure force per unit area and do not relate to torque in any direct way.
