ABSTRACT
A mechanism is a combination of rigid bodies so connected that the motion of one will produce a definite and predictable motion of others , according to a physical law. Alternatively, a mechanism is considered to be a kinematic chain in which one of the rigid bodies is fixed . An exam pIe of a mechanism is the slider crank shown in Figure 1 . 1 (a) . Instruments , watches , and governors provide other examples of mech anisms.
