Q 1 Blocks A 20 kg and B 28 kg are connected to cylinder C 45 kg by separate ropes passing over two smooth pulleys as shown The ropes are attached to the center of the cylinder where force P is also applied Assume the pulleys have negligible mass and cylinder C rests on a smooth surface with negligible friction a Determine the contact force between the cylinder and the ground as well as the magnitude of the applied force P necessary to maintain equilibrium if 0 15 b Determine the maximum angle for which equilibrium can be maintained assuming the orientation of the two other ropes remain the same Find the corresponding magnitude of force P in this scenario B 12
