Q1: During a tensile test of steel bar with circular cross-section (10mm diameter and 100mm length)), the force was 1.964 kN when the elongation 0.0125%. Find: (9 marks) a) The modulus of Elasticity of the steel. b) The stress when the applied force was 3 kN. c) The yield stress if the yield strain is 1%
