Beam AB has a negligible mass and thickness, and supports the 200-kg uniform block as shown in (Figure 1). It is pinned at A and rests on the top of a post, having a mass of 20 kg and negligible thickness. Part A V Determine the two coefficients of static friction at B and at C so that when the magnitude of the applied force is increased to 330 N, the post slips at both B and C simultaneously.
