Each gear has a mass of 2 kg and a radius of gyration about its pinned mass centers A and B of k_g = 40 mm. Each link has a mass of 2 kg and a radius of gyration about its pinned ends A and B of k_l = 50 mm. If originally the spring is unstretched when the couple moment M = 20 N • m is applied to link AC, determine the angular velocities of the links at the instant link AC rotates θ = 45°. Each gear and link is connected together and rotates in the horizontal plane about the fixed pins A and B.
