Question

there are n rotor on the shaft when subjected to torsional vibration there will mcq​

Answer 1

Answer:

There will be Node formation. The number of nodes formed will be equal to the number of rotors minus one,i.e. n-1

Explanation:

When there are n no. of rotors present on the shaft for the torsional vibration to occur there is a need for the rotors to move at least one in the opposite direction and others in the same direction.

For example,

A three-rotor system will have maximum of two nodes.

The node is the part where the shaft does not twist so the shaft is clamped at this section and the other two sections vibrate as two separate other shafts that have the same frequencies.
