Determine the reaction forces at the joints and the crank torque of the slider-crank linkage in the posture shown. For the constant angular velocity w2 = 210 rad/s, the known kinematics are: 3 = 7 670 rad/s/s, AG3 = -7820 + 4876j ft/s/s, and AG4 = -7850 ft/s/s in x-direction. The weights and mass moments of inertia of the links are w3 = 3.40 lb, w4 = 2.86 lb, IG2 = 0.352 in lb ss, and IG3 = 0.108 in lbss. .
