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 = 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. 12 #

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.
