Experiments

1 Determination of natural frequency, logarithmic decrement, damping ratio and damping coefficient in a single degree of freedom vibrating systems (longitudinal and torsional)

2 Balancing of rotating masses

3 Determination of critical speed of a rotating shaft

4 Determination of equilibrium speed, sensitiveness, power and effort of Porter/Proell /Hartnell Governor.

5 Determination of Pressure distribution in Journal bearing

6,7 Study of different types of cams, types of followers and typical follower motions. Obtain cam profile for any two types of follower motions and types of followers 

8 Determination of Fringe constant of Photo­elastic material using. a) Circular disc subjected to diametral compression. b) Pure bending specimen (four­point bending).

Demonstration Experiments (For CIE)
