Gears A and B have a mass of 50 kg and 15 kg, respectively. Their radii of gyration about their respective centers of mass are kC = 250 mm and kD = 150 mm. If a torque of M = 200(1 − e−0.2t) N • m, where t is in seconds, is applied to gear A, determine the angular velocity of both gears when t = 3 s, starting from rest.
