Kinematics of Machines

THIS is a carefully written elementary text-book dealing with the subject from the Reuleaux standpoint. In the first chapter the author introduces the notions of kinematic links and chains and the pairing of elements, and gives some fundamental propositions relating to degrees of freedom and constraint, and to instantaneous centres and centrodes in plane motion.Kinematics of Machines.By R.
