A tension test was performed on a specimen having an original diameter of 12.76 mm and a gage length of 56.97 mm.The data are listed in the table. Plot the stress-strain diagram, and determine approximately the modulus of elasticity, the ultimate stress, and the fracture stress. Use a scale of 20 mm = 50 MPa and 20 mm = 0.05 mm/mm. Redraw the linear-elastic region, using the same stress scale but a strain scale of 20 mm = 0.001 mm/mm. Also, determine the 0.2% yield stress.
