    all mechanisms are made up of a series of four links. The basic four bar link is shown below. When the input link rotates the output link may for example swing back and forth. Note that the fourth link is the frame of the machine and it is rigid and unable to move. With experience you should be able to identify the four bar chains in a mechanism

    Mechanism: 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. Fig.1.20 Slider crank and four bar mechanisms
