A cоrd pаsses оver а frictiоnless pulley аs shown in the figure. One end of the rope is attached to block B and force P is applied to the other end of the cord. The weight of block A is 500 lb and the weight of block B is equal to 1,100 lb. The coefficient of friction between the two block is equal to 0.40 and the coefficient of friction between block B and the floor is equal to 0.20. a)Determine if the system is in equilibrium if the force P = 500lb. b)Find the maximum force P for which the system is in equilibrium, assuming that slipping will occur between block B and the floor. Show all your work to receive full points. Note that the shape is not drawn to scale.
