Basically.brakes are devices for controlling the flow of motion in machines,and in this respect they resemble clutches; clutches start the flow while brakes arrest it.Before the engagement of a clutch or a brake,one of the two members in the device is moving while the other is stationary) after the engagement of a clutch both members are moving at the same speed.while after the application of a brake the moving member is either slowed down or stationary.In both cases the desired effects are produced by devices that are so alike,structurally,that they can sometimes serve in either capacity.
In arresting the motion of bodies,brakes must be capable of absorbing kinetic energy.Even when acting on translating bodies (like automobiles) most brakes are designed to act on rotating mechanical elements and to absorb energy either mechanically,hydraulically,or electrically.Mechanical brakes are the most common; they dissipate kinetic energy in the form of heat generated by mechanical
