A 60-kg uniform circular plate is welded to two elastic rods, which have fixed ends at supports A and B as shown. The torsional spring constant of each rod is 200 N·m/rad, and the system is in equilibrium when the plate is vertical. Knowing that the plate is rotated 2° about axis AB and released, determine 

(a) The period of oscillation, 

(b) The magnitude of the maximum velocity of the mass center G of the plate.
