KINEMATICS OF MACHINERY -Srikanth Rangdal
Objective:
The Subject aims at introducing an Engineering Student with the concept of designing machines
without any consideration of forces acting. It requires a high Visualization Skills of Geometry in Motion & is a
key to the accurate operation of any Machine as it determines the geometric structure required for the
Machine to fulfill the task it is meant for.
