Supports for Rigid Bodies:
In this unit, you have learnt to classify various types of supports and constraints, rollers, rockers, ball and socket joints, cables, short links, pins, frictional surfaces, and hinges (all these are examples of support connections). These associations offer resistance to the movement of the bodies which are called reactions. Following Tables 1 and 2 give the several types of connections and their reactions.
