A homogeneous 150-kg vertical bar AB is raised from rest at ? = 0° by means of the parallel swinging bars of negligible weight, with a constant moment ? = 5 kN-m applied to the lower link at C. Determine the angular velocity and the angular acceleration of the links and the forces at A and B at the instant ? = 34°. (I have seen a solution on this sight but there seems to be an error in the integration step, please clarify integration)

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
