The uniform 36-lb bar is released from rest in the horizontal position shown and strikes the fixed corner B at the center of percussion of the bar. Determine the t-component of the force exerted by the bearing O on the bar just prior to impact, during impact, and just after impact. The t-component is positive if it acts in the t-direction.

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 mobile crane is symmetrically supported by two outriggers at A and two at B to relieve the suspension of the truck upon which it rests and to provide greater stability. If the truck, crane, and counter-weight have a total mass of 18-tonnes and center of mass at G1, while the boom has a mass of 1.8-tonnes and a center of mass at G2, determine the critical angle where tipping starts to occur when the boom is supporting a load having a mass of 3-tonnes. Plot the total reactions at A and B (in kN) as functions of θ from θ=0° to the critical angle.

The Charpy impact test is performed using the pendulum which has a mass m, mass center at G and radius of gyration ka about G as shown in Fig.7. Determine the distance r, from the pin at A to the P where the impact with the specimen S should occur so that the horizontal force at A is essentially zero during the impact. Assuming the specimen absorbs all the pendulum's kinetic energy gained during the time it falls and thereby stops the pendulum from swinging when 0 = 0°. TP.
