  UNIVERSAL VIBRATION APPARATUS.
A comprehensive unit to perform the vibration experiments.Three different modules are provided upon which three batches can work simultaneously. Work of assembly & dismantling is reduced to much extent, which is its distinct advantage over conventional common frame type units.
Experiments-
Module I
1.Simple pendulum.
2. Compound pendulum 
3. radius of gyration of bi-filar suspension.
4. Tri-filar suspension.
Module II
1. undamped torsional vibrations of single rotor system.
2. Damped torsional vibrations of single rotor system. 
3. Undamped torsional vibrations of double rotor system. 
Module III
1. free vibrations of helical coiled spring. 
2. free vibrations of spring mass system.
3. forced damped vibrations of a spring mass system.
4. Lateral vibrations of simply supported beam.
5. Verification of Dunkerleys rule.

  CAM ANALYSIS APPARATUS  
To study the cam profiles and performance of cam & follower system. A cam shaft supported by ball bearing upon which three different types of cam can be mounted. A push rod for follower is supported vertically. A variable speed motor rotates the cam. A dial gauge permits plotting of follower displacement with respect of cam position. Jump speed & effect of weight & spring force on jump speed can be studied.

  WHIRLING OF SHAFTS DEMONSTRATOR                                     
A base upon which bearing holders and driving motors are coupled.Different bearing can be fitted in a bearing holder to provide different end conditions for test shafts. A variac controls speed of driving motor. The unit demonstrates the phenomenon of whirling of shaft with single rotor. No necessity of applying pretension to shaft. Thus giving a stress free shaft , where equations of deflection can be applied without doubt . Because of single rotor system good results 
comparable with theory. Demonstration of true running of shafts after passing the critical (whirling ) speed.
