*8–52. beam ab has a negligible mass and thickness, and supports the 200-kg uniform block. it is pinned at a and rests on the top of a post, having a mass of 20 kg and negligible thickness. determine the two coefficients of static friction at b and at c so that when the magnitude of the applied force is increased to p=300 n, the post slips at both b and c simultaneously.
