As a laboratory instructor, you need to explain the manufacture of steel to students. Explain this process and briefly explain the relevant treatment process.

A cylindrical rod with a length of 380 mm and a diameter of 10 mm is to be subjected to a tensile load. The rod must not experience plastic deformation or an increase in length of more than 0.9 mm when a load of 24.5 kN is applied. Which of the four materials listed in table are possible candidates? Justify your answer. Material Elastic Modulus, GPa Yield Strength, MPa Tensile Strength, MPa 110 ETT 70 207 101 Copper Aluminum alloy Steel Brass alloy 248 255 448 345 289 420 551 420 * Plastic deformation is defined as a process in which the object due to applied force changes its size or shape in a way that is not reversible
