Gears C and H each have a weight of 0.4 lb and a radius of gyration about their mass center of k_A = k_B = 2 in. The uniform link AB has a weight of 0.2 lb and a radius of gyration of k_A = 3 in., whereas link DE has a weight of 0.15 lb and a radius of gyration of k_B = 4.5 in. If a couple moment M = 3 lb · ft is applied to link AB and the assembly is originally at rest, determine the angular velocity of link DE when link AB has rotated 360°. Gear C is fixed from rotating and motion occurs in the horizontal plane. Also, gear H and link DE rotate together on the same shaft at B.
