Forces acting on machine elements created by virtue of their motion
Get a keen insight in to the forces generated due to motion, that are otherwise absent while the engine is at rest.


  • Engineering Mechanics fundamentals


IC Engines are some of the most complex machines and are widely used in automobiles. Understanding the dynamic forces acting on these machines are very important to visualise the design intent required in manufacturing these machines. This course provides the fundamental forces acting on recirocating engines. Various forces that arise in the two vital components of theengine namely the connecting rod and the crank are derived based on principles of engineering mechanics and are explained in full detail. Also some tutorial sessions are handled involving some fundamental problems involving the force components derived to provide an in depth understanding if the magnitude of these forces.

Once the learner is able to get an idea of the mangnitude of these forces, he / she would be in a position to appreciate the involvement of force magnification  by virtue of high speed motion of the egine parts. Various component forces act in various directions leading to complex stresses in the parts such as connecting rod, crank pin, crank shaft bearings and so on.

Such an understanding is very vital to pursue the studies of mechanical engineering related to forces arising due to motion in machinery. Hence the term dynamic force analysis is rather apt since these forces exist so long as the engine is in motion and cease to exist when the engine comes to rest. With fundamental knowledge of engineering mechanics solving for forces in static equilibrium, this course sheds some light on forces that could be generated due to the motion of parts.

Being a beginning level researcher and a full time assistant professor at the department of Mechanical Engineering, my research interests include severe plastic deformation of FCC metals, solid state bonding of FCC metals by such plastic deformation techniques, various fusion based metal joining techniques and Finite Element Modelling of such processes. With most of works in the pipeline, few had been published. Looking forward to make an impact in the area of tailor fabrication of high strength low weight metals by severe plastic deformation techniques.
