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.

The body A with a mass of 50 kg is in equilibrium with the help of the pulling force generated in the AB and AC cables in the middle of the inclined plane and the friction force between the curved surface and the object. The friction force is on the line of motion of body A and develops in the opposite direction to the movement in the direction of the arrow shown in the drawing. Since the pulling force in AB and AC cables is 15.1 and 22.1 N, respectively, calculate the balancer friction force acting on the object vectorially? (g = 9.81 m / s'2)
