The correct answer is (c) Dependent on mass moment of inertia

For explanation: The free torsional vibrations of a single motor system depends on the following factors:

Modulus of rigidity, Polar moment of inertia, mass moment of inertia and length of the shaft.

In a gearing system, pump speed is one third of the motor. Shaft from motor is 6 cm in diameter and 30cm long, the impellar shaft is 10cm diameter and 60cm long. Mass moment of inertia is 1500 Kg-m^2, C = 80Gn/m^2. Neglecting the inertia of shaft and gears calculate the frequency of free torsional vibrations in Hz.
