Problem 3 The beam AB has a negligible mass and thickness and is subjected to a triangular distributed loading, as shown in Figure 3. It is supported at one end by a pin and at the other end by a post having a mass of 50 kg and negligible thickness. The coefficients of static friction at B and C are μB=0.2 and μc=0.4, respectively. (a) Draw the free body diagram of AB and BC, respectively. (b) Start by assuming the post slips at C, determine the minimum force P needed to move the post. 800 N/m -2 m- 400 mm Figure 3 B 300 mm C
