C. Suppose that a certain fraction of the power produced by a 350 MW coal plant is offset bywind power. Assume that when the coal plant runs at its constant rated power it has an efficiencyof 37%, but that when it needs to be ramped up and down to compensate for the wind powervariations its efficiency is reduced by according to e=0.37-0.00001p², where p is the amountof wind power. Find the percentage increase in emissions that results when 90 MW of the 500MW is generated by wind power instead of coal. What will be the maximum power of the plant?

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.
