The results of a tensile test on a specimen of mild steel are as follows: original diameter = 20mm; original gauge length = 40 mm; proportional limit load = 80kN; extension at proportional limit = 0.048 mm; yield point load = 85 kN; maximum recorded load = 150 kN; final length between gauge points = 55.6 mm; and final minimum diameter (neck) = 15.8 mm. Calculate: (a) The modulus of elasticity for the mild steel (6) The proportional limit stress (c) The ultimate tensile stress (d) The percentage elongation (e) The percentage reduction in area (5) (2.5) (2.5) (2) (3)
