What is the torsion constant of this pendulum

Reference no: EM13238261

A torsion pendulum is made from a disk of mass m = 5.7 kg and radius R = 0.67 m. A force of F = 43 N exerted on the edge of the disk rotates the disk 1/4 of a revolution from equilibrium.

1. What is the torsion constant of this pendulum?

2. What is the minimum torque needed to rotate the pendulum a full revolution from equilibrium?

3. What is the angular frequency of oscillation of this torsion pendulum?
