(a) A non-cold-worked 1040 steel cylindrical rod has an initial length of 100 mm and initial diameter of 7.50 mm. is to be deformed using a tensile load of 18,000 N. It must not experience either plastic deformation or a diameter reduction of more than 1.5 x 10-2 mm. Would the 1040 steel be a possible candidate for this application? Justify your choice(s) using calculations. For the 1040steel: Elastic modulus is 205 GPa, Yield strength is 450 MPa, and Poisson’s ratio is 0.27. (b) If you are asked to perform a strain hardening process to increase the yield strength so the steel can be used in another application with larger force load. How much cold work would be required to reduce the diameter of the steel to 6.0 mm?
