If the sprocket S is turning with an angular velocity ?S = 6 rad/s, and an angular acceleration of ?S = 2 rad/s^2. Find angular velocity and angular acceleration of link AB. Note that link AB shares an axis of rotation with sprocket S, but is free to rotate separately from S (it’s not attached to the sprocket S). The pin at C is attached to one of the chain links, and is moving vertically downward.

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.
