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.

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.
The push rod for follower is supported vertically, which can adopt three different types of followers. Cams and followers can be changed easily. A variable speed motor rotates the cam. A dial gauge permits plotting of follower displacement with respect to cam position. By operating the system at different Speeds, jump speed can be found and also the effect of weight and spring force on jump speed can be studied. Jump can be visualized also with the help of stroboscope (it is not supplied With the product).
