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 create…

The 10-oz disk shown spins at the rate w1 = 750 rpm, while axle AB rotates as shown with an angular velocity w2. Determine the maximum allowable magnitude of w2 if the dynamic reactions at A and B are not to exceed 0.25 lb each.

The uniform, thin 5-lb disk spins at a constant rate w2 = 6 rad/s about an axis held by a housing attached to a horizontal rod that rotates at the constant rate w1 = 3 rad/s. Determine the couple that represents the dynamic reaction at the support A.

A torque T of 100 N-m is applied to a wheel D having a mass of 50 kg. a diame- ter of 600 mm, and a radius of gyration of 280 mm. The wheel D is attached by a light member AB to a slider C having a mass of 30 kg. If the system is at rest at the instant shown, what is the acceleration of slider C? What is the axial force in member AB? Neglect friction everywhere, and neglect the inertia of the memberAB. (Draw FBDs)
