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.

The mechanism shown is one of two identical mechanisms attached to the two sides of a 200-lb uniform rectangular door. Edge ABC of the door is guided by wheels of negligible mass that roll in horizontal and vertical tracks. A spring with a constant k is attached to wheel B in such a way that its tension is zero when 0 = 30°, Knowing that the door is released from rest in the position 0 = 45° and reaches the vertical position with an angular velocity of 0.6 rad/s, determine the spring constant k.
Two identical 4-lb slender rods AB and BC are connected by a pin at B and by the cord AC. The assembly rotates in a vertical plane under the combined effect of gravity and a 6-lb·ft couple M applied to rod AB. Knowing that in the position shown the angular velocity of the assembly is zero, determine (a) the angular acceleration of the assembly, (b) the tension in cord AC.
The rotor of an electric motor has an angular velocity of 3570 rpm when the load and power are cut off. The 65-kg rotor, which has a centroidal radius of gyration of 175mm, until it reaches the maximum speed of 5250 rpm. Knowing that the kinetic friction results in a couple of magnitude 4.5 N.m exerted on the rotor, determine the number of revolutions that the rotor executes, before achieving its maximum speed and the time it took.
