The theory of machines lab is equipped with various test rigs to understand the function of a mechanism in common machine tools, to construct velocity and acceleration diagram in planar mechanisms, to analyse the inertia forces involved in an internal combustion engine, to determine the various possible motions between cam-follower and gears assemblies and to understand and apply the concept of free and forced vibration in determination critical or whirling speed of shaft. This lab has inhouse universal vibration apparatus, motorized gyroscope, various governors, journal bearing test rig, coroillis acceleration of component test rig, whirling of shaft apparatus etc. to perform various experiments.
