Question

The speed at which the shaft runs, so that the deflection of the shaft from the axis of rotation becomes infinite, is known as
1. whipping speed
2. damping speed
3. resonant speed
4. gravitational speed

Answer 1

Correct Answer - Option 1 : whipping speed

Concept:

Whipping speed:

• It is the speed at which the shaft runs, so that the deflection of the shaft from the axis of rotation becomes infinite.
• This speed is also known as critical or whirling speed. Its depends on eccentricity of the centre of gravity of rotating mass from the axis of rotation of the shaft
