Chapter 14, Problem 58P
The 50-lb block rests on the rough surface for which the coefficient of kinetic friction is μk = 0.2. A force F = (40 + s2) lb, where sis in ft, acts on the block in the direction shown. If the spring is originally unstretched (s = 0) and the block is at rest, determine the power developed by the force the instant the block has moved s = 1.5 ft.

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)
