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 mp 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 the post slips at both B and C simultaneously.

Given:

mp = 50 kg

P = 150 N

w = 800N/m

a = 2 m

b = 400 mm

c = 300 mm

d = 3

e = 4

F=µN

F=N
