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...

A cylindrical car component with 7 mm diameter is to be manufactured. The component is required to possess a yield strength of at least 700 MPa and an elongation to fracture of at least 11%. For this purpose, you use a cylindrical steel 1040 rod with an initial diameter of 9 mm. The percent cold work cannot exceed 40% during any single cold deformation step in order to avoid cracking. Using the diagram below, describe your manufacturing procedure for this...
