Problem 1 (10 pts) It is required to manufacture a 2.5 mm diameter copper rod from larger diameter stock by drawing. The rod should have a tensile strength of 300 MPa or more, a yield strength of 200 MPa or more, and ductility of 10% or more. Determine (a) the range of%CW which will allow achieving those properties, and (b) within this range clearly pick a certain%CW and determine the corresponding diameter of the starting stock. yield strength (MPa) tensile...
