A71 kg solid sphere with a 12 cm radius is suspended by a vertical wire. a torque of 0.41 n·m is required to rotate the sphere through an angle of 0.76 rad and then maintain that orientation. what is the period of the oscillations that result when the sphere is then released?

5.47 s

Explanation:

Given

mass of solid sphere

radius of sphere

Torque Applied

Inclination Produced

Now we know that time Period of Torsion Pendulum

where

C is torque required to produce unit deflection

Moment of Inertia of solid sphere

this is poiselle's equation from fluid mechanic in physics. mech eng
