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.

On the attached drawing, is the allowance between "shaft C" and "hole D" positive or negative?
A machine part to be machined may be made either from an alloy of aluminum or steel. There is an order for 8000 units. Steel costs P3.80 per kg. while aluminum costs P8.70 per kg. If steel is used, the steel per unit weighs 110grams, for aluminum, 30 grams. When steel is used, 50 units can be produced per hour, for aluminum, 80 units per hour with aid of tool costing P640, which will be useless after the 8,000 units are finished. The cost of the machine and the operator is P10.80 per hour. How much is the cost per unit if aluminum is used?
