An annealed-steel tensile specimen (E=200GPa) has a 12 mm minimum diameter and 50 mm gauge length. Maximum load is reached at 68.6 kN and fracture occurs at 44.1 kN. The minimum diameter at fracture is 10 mm. wwwww (1) What is the tensile strength? (1) Why does fracture occur at a lower load than maximum load? (1) Determine the true fracture stress. (iv)Determine the true strain at fracture. (v) What is the engineering strain at fracture? (vi) What is the deformation when a tensile stress of 100 MPa is applied?
