Introduction: Mechanism and Machine: A mechanism is a constrained kinematic chain. This means that the motion of any one link in the kinematic chain will give a definite and predictable motion relative to each of the others. Usually, one of the links of the kinematic chain is fixed in a mechanism. Whereas a  machine is…
