a) A standard mild steel tensile test specimen has a diameter of 16mm and a gauge length of 80mm. the specimen was tested to destruction and the following results obtained, Load at yield point = 87KN Extension at yield point = 173 x 106 m Ultimate load = 124KN Total extension at fracture = 24mm Diameter of specimen at fracture = 9.8mm Cross-sectional area at fracture = 75.4mm² Cross-sectional area "A" = 200mm² Compute the followings: i. Modulus of elasticity of steel. Ultimate tensile stress. ii. iii. Yield stress iv. Percentage elongation. a) A standard mild steel tensile test specimen has a diameter of 16mm and a gauge length of 80mm. the specimen was tested to destruction and the following results obtained, Load at yield point = 87KN Extension at yield point = 173 x 106 m Ultimate load = 124KN Total extension at fracture = 24mm Diameter of specimen at fracture = 9.8mm Cross-sectional area at fracture = 75.4mm² Cross-sectional area "A" = 200mm² Compute the followings: i.
