Mechanism design course would help students in achieving the following objectives: To help in understanding different types of mechanisms and underlying concepts of kinematics. To build mathematical models of mechanisms and develop position, velocity and acceleration relations. To understand the dynamic characteristics of planar mechanisms.


CLO-1: Apply the kinematic fundamentals for the graphical synthesis of linkages. (C3)
CLO-2: Analyze the position, velocity and acceleration of different mechanisms using graphical and analytical techniques. (C4)
CLO-3: Design and analyze mechanisms using linkages, cam-follower systems, gear trains and relate their analytical and graphical solutions.  (C6)
