A tensile-test specimen has a gauge length of 50 mm and a cross-sectional area of 100 mm^{2}. It yields at 48 000 N, when the gauge length is 50.23 mm (this is the 0.2 % offset yield point). The maximum load of 87 000 N is reached at a gauge length of 64.2 mm. Fracture occurs at a gauge length of 67.3 mm, and the neck area at fracture is 53 mm^{2}. Determine (a) the yield strength (MPa), (b) the modulus of elasticity (GPa), (c) the tensile strength (MPa), (d) the percent elongation (%) and (e) the percent reduction in area (%).
