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.

Question

At the instant shown, link CD rotates with an angular velocity of W = 7.5 rad/s. If it is
subjected to a couple moment M = 560 N-m, determine the magnitude of the
angular acceleration (rad/s2) of link CD. The block has a mass of 50 kg and center of
mass at G. Neglect the mass of links AB and CD. (Hint, since the mass of link AB or
CD is negligible, the external force or moment acting on it sums up to 0.) Please pay
attention: the numbers may change since they are randomized. Your answer must
include 2 places after the decimal point, and proper unit. Take g = 9.81 m/s2.
