A torsion pendulum is constructed of a copper rod of radius 4mm and length 0.55m is attached to the end of the copper rod and set into oscillation by twisting the rod/sphere. The sphere is rotated 10.2 degrees and then released. a. if the maximum velocity of the sphere is 1.15 rad/s, what is the oscillation? b. What is the torsion constant of the rod? c. if the hollow sphere was replaced with a solid sphere instead (which has 10 times the mass of the hollow sphere,) what period of oscillation would result?
