Each of the two links has a mass of 1.8 kg and a centroidal radius of gyration of 75 mm. The slider at B has a mass of 3.5 kg and moves freely in the vertical guide. The spring has a stiffness of 7.2 kN/m. If a constant torque M = 21.4 N-m is applied to link OA through its shaft at O starting from the rest position at 0 = 45, determine the angular velocity of OA when 0 = 0. 45 B 250 mm mm 500 mm M 250 mm Answer: w = i 14.285 rad/s
