Prerequisites for the graduate-level course are Kinematics, Dynamics, differential equations, motion

simulation, displacement, velocity, acceleration, force, torque, power, Newton’s motion laws, vibration, Gyroscopic Effect, Cams, Bearings.

Course Objectives

The objective of the lab is to understand the kinematics and dynamics of

mechanical elements such as linkages, gears, cams and learn to design such elements to accomplish desired motions or tasks.
