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

Bar BC of the linkage slides in the collar D. If bar AB
is rotating clockwise with constant angular velocity of 12 rad/s, determine
the angular velocity of BC when it is in the horizontal position shown.

collar, on bar BC)
Hint 2: since you can visually decide the direction of velocities at point B
and D', find the Instantaneous Centre of these 2 points, therefore figure out
the angular velocity of BC
