Question

The torque transmitted by a cylindrical shaft is to be measured by using two strain gauges. The angles for mounting the strain gauges relative to the axis of the shaft for maximum sensitivity are

1. ±45°
2. ±60°
3. ±90°
4. ±180°

Answer 1

Correct Answer - Option 1 : ±45°

The torque transmitted by a cylindrical shaft is to be measured by using two strain gauges. For maximum sensitivity, the strain gauges aligned at ±45° relative to axis of the shaft.
