OBJECTIVES
• To understand the layout of linkages in the assembly of a system/machine.
• To study the principles involved in assessing the displacement, velocity and acceleration at any point in a link of a mechanism
• To analyse the motion resulting from a specified set of linkages in a mechanism.
