OBJECTIVES:

 To understand the basic components and layout of linkages in the assembly of a system machine.  To understand the principles in analyzing the assembly with respect to the displacement, velocity, and acceleration at any point in a link of a mechanism.  To understand the motion resulting from a specified set of linkages, design few linkage mechanisms and cam mechanisms for specified output motions.  To understand the basic concepts of toothed gearing and kinematics of gear trains and the effects of friction in motion transmission and in machine components.
