Question 1 (70 pts): Consider a cylindrical metal 16mm in diameter and 70mm long is pulled in tension. It is known that the yield strength and elastic (Young's) Modulus of the material are 350MPa and 200GPa, respectively, and its Poisson's Ratio is 0.3. (a) Determine whether the deformation is elastic or plastic when 80KN is applied. (b) Calculate specimen elongation (l) and reduction in diameter (d) when 60KN is applied? (c) What are the values l and d when the load is released? (d) If necking occurs at a load of 98KN, determine the UTS of the metal. (e) Calculate the ductility in terms of \% E.L. if the length of the specimen at the fracture point is 76.0mm
