Determine the reaction forces at the joints and the external torque applied to input link 2 of the four-bar linkage in the posture shown. For the constant angular velocity = 200kd, the rad known kinematics are 3 = -6 500k,4 = 240k rad rad and AGA = -800i - 2 110^j. The weights and mass moments of inertia of the 5, AG3 lb . 17in, RB04 = ft 262^j S links are w3 = 2.65 lb, w = 6.72 lb, 1G = 0.023 9 in lb s, and IGA = 0.531 in lb s.
