Asked by Mike Lian
A uniform beam AB of mass 84.78 kg rest against the smooth wall at A and the rough horizontal floor at B. The coefficient of static friction between the beam and the horizontal floor is U=0.249.
Calculate the magnitude of the horizontal force P, in N, such that the end B has IMPENDING MOTION TO THE LEFT. Assume g = 9.81 m/s^2.
