Static Dynamic Balancing Apparatus
This equipment is designed for carrying out the experiment for balancing a rotation mass system. The apparatus consists ofa stainless steel shaft fixed in a rectangular frame. A set of four blocks with a clamping arrangement is provided. For static balancing, each block is individually clamped on shaft and its relative weight is found out using cord and container system in terms of number of steel balls. For dynamic balancing, a moment polygon is drawn using relative weights and angular and axial position of blocks is determined. The block are clamped on shaft is rotated by a motor to check dynamic balance of the system. The system is provided with angular and longitudinal scales and is suspended with chains for dynamic balancing.

Interference Undercutting
The board shows the demonstration of this phenomenon of Interference and Undercutting. When we rotate the teeth in anticlockwise direction, as the teeth is undercut is gives us a smooth working. When we give a rotation in clockwise direction, we can observe that the rack tip will be resisted by the tooth flank thus giving interference.
Cam Analysis Apparatus
The apparatus is designed to study the cam profiles and performance of cam and follower system. The apparatus consists of a shaft supported by ball bearings upon which three different types of cams can be mounted.

Both end fixed and one end free, one end fixed. A Variac provided control of driving motor. The unit demonstrates the phenomenon of whirling of shafts with single rotor. As the test is destructive, after the test cannot be used, hence the unit only demonstrates the principle.
However, results obtained are closer to theory, as compared to those with bare shafts. Also, It can be demonstrated that, after passing whirling speed, shaft again starts running true.
