Blocks A and B are connected by a cable which passes horizontally through each block and the wall as shown in figure 3. The cable turns around two polished without friction. The mass of block A is 550 kg and that of block B is 1000 kg. Knowing that block B is placed on a horizontal plane and that the force P is also horizontal, (a) Draw the free body diagram of block A and block B (separately); (b) Determine the force of P that must be exceeded to lift the block A (imminent movement case) and the tension in the cable.
