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. www 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 = 15⁰. 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 3 4 P
