A 20kg slender rod AB is pinned to a roller at A that slides freely along the slot as shown in the figure below. The rod is released from the rest at an angle of 30. At the same time, a couple moment of M = 5 N.m in clockwise direction is applied at its centre of gravity. If immediately after the release the acceleration of the roller at A is 43m/s, determine the reaction forces at the pin connection at Point A.

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.
