Correct answer is (c) Gearing teeth always in contact

Easy explanation: For the free torsional vibration of a geared system there should be no backlash in geared system and the inertia of the shaft, gears should be considered negligible and the gearing system should always be in contact.

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.
