DYNAMOMETER

A dynamometer is an apparatus for measuring power, or the rate of doing work, that is for measuring the force exerted by men, animals, or motors in overcoming some resistance. The resistance of a spring to extension or compression is the basis in some forms, weights or friction brakes are used in others. In absorption dynamometers, exemplified by friction brakes, the work done is dissipated as heat; in transmission dynamometers, the energy is utilized after measurement.
