Question

The following data refer to a tensile test conducted on a mild steel bar : diameter of the specimen = 20 mm ,length of the specimen = 200 mm extension at a load of 40 kN = 0.12mm ,Load at yield point = 80kN Maximum load = 150 kN, Total extension = 50 m, Neck diameter = 15 mm. Determine (i) young’s modulus (ii) yield stress (iii) ultimate stress (iv) percentage elongation and (v) percentage reduction in area.
