Each gear has mass of 2 kg and a radius of gyration about its pinned mass center A or B, respectively of k_g = 40 mm. Each link has a mass of 2 kg and a radius of gyration about its pinned end A or B, of k_∫ = 50 mm. If originally the spring is unstretched when the couple moment M = 20N · m is applied to link AC, determine the angular velocity of the links at the instant link AC rotates θ = 45°. Each gear and link are connected together and rotate about the fixed pins A and B.
