Course Objectives

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.

Course Learning Outcomes (CLO)

  1. CLO-1: Analyze the graphical and analytical techniques for position, velocity and acceleration analysis of planar mechanisms. (C4)
  2. CLO-2: Model mechanisms of practical nature like Quick return, straight line, Dwell mechanisms, CAM-Follower and Gear Trains. (C3)
  3. CLO-3: Demonstrate working of mechanisms using MATLAB/Simulink based SimMechanics software tool in term projects. (P3)
