52090 provides study of Strain Gauge and their application for measurement of Torque, It helps to study bridge configuration of Strain Gauge and the signal conditioning circuits required to measure Torque. It uses cantilever beam arrangement to produce Torque on Strain Gauge.
The Strain Gauge are firmly cemented to the cantilever at the point where the Torque is produced. Torque developed changes the resistance of Strain Gauge which is detected by full bridge configuration. Seven segment LED display shows Torque in kg.m units. Different weights are provided to perform linearly and sensitivity experiments.

Object:

1. To study Torque measurement using strain gauges and cantilever assembly.
2. To determine the linear range of operation of Torque measurement.
3. To determine sensitivity of the trainer.
