The beam AB has a negligible mass and thickness and is subjected to a triangular distributed loading. 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. 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 = 150 N, the post slips at both B and C simultaneously. Take F = 940 N/m. (Figure 1) Figure -2 m 400 mm 300 mm < 1 of 1 > Part A Determine the coefficient of static friction at B Express your answer using three significant figures. HB = Submit Part B HC = Submit ΕΠ ΑΣΦ VI Determine the coefficient of static friction at C. Express your answer using three significant figures.
