Make a complete dynamic analysis of the slider-crank linkage in the posture when θ2 =

120◦. For the constant angular velocity ω2 =

24 rad/s cw, the known kinematics are θ3 = −9◦, RB = 0.374 m, α3 = 89.3 rad/s2 ccw, AB =

40.6ˆi m/s2, and AG3 = 40.6ˆi − 22.6ˆj m/s2. The constant crank torque is T12 = 60 N · m. The masses and mass moments of inertia of the links are m2 = 1.5 kg, m3 = 3.5 kg, m4 = 1.2 kg, IG2 = 0.010 N · m·s2, and IG3 = 0.060 N ·m·s2.
