Static & Dynamic Balancing Apparatus


The apparatus enables the students to experimentally balance a rotating mass system and to verify the analytical relations. The apparatus consists of a 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 on shaft and 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 positions of blocks are determined. The blocks 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.
