A cord passes over a frictionless pulley as 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 300 lb and the weight of block B is equal to 1,000 lb. The coefficient of friction between the two block is equal to 0.30 and the coefficient of friction between block B and the floor is equal to 0.35. a) Determine if the system is in equilibrium if the force P = 600lb. 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, including FBDs, to receive full points. Note that the shape is not drawn to scale.
