About Course

Kinematics is a branch of theory of machines which deals with the study of relative motion of various elements of machine without taking into consideration the forces which act upon them.Kinematics of machines is a very special course for the mechanical, aeronautical and automobile engineers. This course deals with distinctive features and construction of the mechanism with an introduction to the subject matter and nomenclature, and will cover direct and inverse kinematics, velocity and acceleration analysis, cam and follower motion and kinematic analysis of gear transmission so as to demonstrate various concepts of mechanisms and their constructions by analysing and working out problems relevant to real life applications of mechanisms.Thus, attending this course by mechanical, aeronautical/ aerospace, electrical and biomedical engineers will gain theoretical knowledge about how the mechanism works and then know the machine sare constructed to perform their functionality which are found its application in real life.

What Will You Learn?

  • After completion, the course will help engineers to understand the basic concept of mechanism, machine and related terminologies and the use of kinematic analysis.
  • Exposed to various mechanism and motion transmission elements most used in engineering.
  • Will be able to analyse a mechanism for displacement, velocity and acceleration at any point in a moving link..
  • Have gained the theoretical knowledge tdesign, analysis and construction of cam follower mechanism a per the specific need.
  • Illustrate and explain the design principles, construction and working of gears and gear trains.
