Answer 2

Given:

The mass, moment of inertia of both the shafts in a two-rotor system is the same.

To find:

If the length of one the shaft is doubled what should be the effect on the

length of another shaft?

Explanation:

The vibration in a two-rotor system occurs only if the frequencies of both the rotors are the same.

Like the mass, a moment of inertia of both the shafts are the same then their angular momentum is also the same.

∴L = Iω

∴ L ∝ ω

Hence when the length of one shaft is doubled, then the length of another shaft will be doubled.

Correct option c: doubled
