Blocks A and B have a mass MA and MB, respectively. If the coefficient of static friction between A and B and between B and Cis ps and between the ropes and the pegs D and E ps, determine the smallest force F needed to cause motion of block B . Units Used: kN =103 N Given: ?=45deg s =0.25 MA =100 kg ps = 0.5 MB =150 kg P=30N g=9.81m/s2
