A square bar with an initial size of 13.2 mm is reduced by cold work to 10.7 mm (still square). If the radius of a cylindrical specimen, same material, was reduced by cold work also to 27 mm, what was its initial radius (mm) if the mechanical properties turns out to be similar to the square bar specimen?
Circles of a metal are being punched that will be later stamped into coins. The metal has a shear strength of 32,575 psi. The sheets are 2.1 mm thick. The coin blanks are to be 16.5 mm in diameter. If sheet of metal is expected to produce 50 coin blanks, how much force is required to punch the sheets?
