The 544g collar is free to slide on the smooth rod OA. The rod rotates about pin O at constant angular velocity, é. $2 a ==en + še, = a = RÔ?e, + RÖe, for a circular path, R = radius 2.1 Use N-T coordinates, draw a FBD and a kinetic diagram to determine the minimum value of è for which the collar will maintain contact with the stop at A throughout the rotation. 2.2 Would friction between the collar and the rod affect your result in 2.1?

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.
