Section: A Course Instructor: Prof. Shanthala K Course Name: KINEMATICS OF MACHINES Course Code: 17ME42

COURSE OBJECTIVE: This subject is being taught to the student of IV SEM Eng., students of Mechanical program with a view to enable him/her to 1. Identify mechanisms with basic understanding of motion, 2 Comprehend motion analysis of linkages of planar mechanisms.

3. Analyse velocity and acceleration for various planar mechanisms. 4. Comprehend motion analysis of Gears, gear trains, CAMS

PREREQUISITE(s): Engineering mechanics , Undergraduate mathematics

COURSE OUTCOME: A student undertaking the this subject will be able to

1. Understand and Analyse the motions of linkages of various planar mechanisms

2. Apply the inversions of planar mechanisms of four bar linkages and slider crank chain mechanism.

3. Determine displacement, velocity and acceleration of different planar mechanisms by graphical method

4. Determine displacement, velocity and acceleration of different planar mechanisms by analytical method and design four bar mechanism.

5. Understand the characteristics of gears and analyse various types of gear trains to determine the design parameters like number of teeth and speed 6. Analyze the motion of cams and follower

It is Basic Subject for: Dynamics of machinery.

SUBJECT APPLICATIONS: Automotive Industries, Rotary Machineries, Design of Mechanisms. (Studying kinematics gives engineers insights on

how the machine functions and what design aspects can be modified to achieve a required motion.)
