A torsion pendulum is made from a disk of mass m = 7.2 kg and radius R = 0.74 m. A force of F = 43.1 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?

Q.3 A solid disk with a mass of 36 kg and a radius of 0.7 m is spinning around an axis through its center, it rotates with an angular speed of 3 full turns per second. You drop a 12 kg mass onto the disk at the edge, it sticks to the disk, reducing the angular speed to ws. Next you apply a 30 N force tangentially at the edge of the disk to slow it...
