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.

A 0.20 kg horizontal beam has length L=0.8 m. It is supported by a fulcrum at d=0.55 m from the left end. A 0.15 kg mass ml is suspended at xl=0.15 m from the bar's left end. Another mass mr is suspended at xr=0.65 m from the bar's left end. The system is in equilibrium. How heavy in kg is the mass mr on the right side? Hint: the bar's gravity has a torque if it is not supported by the fulcrum at exactly half way.
