4. Two previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross section, and the other is rectangular during deformation the circular cross section is to remain circular, and the rectangular is to remain as such. Their original and deformed dimensions are as follows: Rectangular (mm) Circular (diameter, mm) 125x 175 15.2 Original dimensions 7.5x 200 Deformed dimensions 11.4 Which of these specimens...

3. You are tasked with strengthening a 1040 steel rod via strain hardening. The component's application dictates a minimum of a 700 MPa yield strength while also maintaining as much ductility as possible. a. What percent cold working would you recommend? What are the associated yield strength and %EL? b. Given a starting diameter of 30mm, what should your diameter be after the prescribed cold working? 1040 Steel SEL Yield streng Mal Duct 400 Cooper 1040 Steel 2001 20 Copper...

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...

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...
