Question

Quizplus · Accepted Answer

Prony brake is a device used to measure the torque of a motor experimentally. It works by applying a known load to the output shaft of the motor and measuring the resulting force or torque. This torque can then be used to calculate the power output of the motor. Although a torque brake is also a device used for measuring torque, it is not as commonly used as a Prony brake in experimental settings. Torque pedal and Prony clutch are not devices used for measuring torque.
