A horizontal bar is used to support a 75-kg object between two walls, as shown in Fig. The equal forces F exerted by the bar against the walls can be varied by adjusting the length of the bar. Only friction between the ends of the bar and the walls supports the system. The coefficient of static friction between bar and walls is 0.41. Find the minimum value of the forces F for the system to remain at rest.

Round off to two significant figures,
F = 897 N
Therefore, the magnitude of the force exerted by the bar on the wall, to balance the system is 897 N.
