5. A tensile test specimen of stainless steel alloy having a diameter of 0.495 in. and a gage length of 2.00 in. was tested to fracture. Stress and strain data obtained during the test are shown below. Determine (all in ksi): a. the modulus of elasticity. 160 b. the proportional limit. c. the ultimate strength. d. the yield strength (0.20% offset). e. the fracture stress. f. the true fracture stress if the final diameter of the specimen at the location of the fracture was 0.350 in.
