Flywheel A of le tire tester drives two wheels B and C simultaneously. The ywheel A has a weight of 600 lb, a 4 ft in radius, and a 2 ft radius of gyration. Wheel B and C weight 64.4lb each, have a 1 ft radius, and may be considered as uniform disks. The wheels are at rest when a 1000 lb-ft counterclockwise couple is applied to wheel A. Determine the number of revolutions of wheel A before the angular speed of wheel C is traveling at 200 rad / sec. Neglect frictional losses at axles A, B, and C
