A dynamometer or "dyno" for short, is a device used for measuring force, torque, or power of a rotating element.

For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (rpm). Power and speed are related by following:

P= Force $\times$ velocity

OR

P = Torque $\times$ angular velocity

Classification

BRAKES: It is device which is used to stop or to retard the motion of the vehicle without skidding and converting kinetic energy into heat dissipation.

DYNAMOMETER: It is the device which measures the power developed by the vehicle or torque developed by the vehicle. This is done by utilizing the amount of heat developed during the breaking of the vehicle.
