A tension test was performed on a steel specimen having an original diameter of 12.5 mm and gauge length of 50 mm. The data is listed in the table. Plot the stress–strain diagram and determine approximately the modulus of elasticity, the yield stress, the ultimate stress, and the rupture stress. Use a scale of 25 mm = 140 MPa and 25 mm = 0.05 mm/mm. Redraw the elastic region, using the same stress scale but a strain scale of 25 mm = 0.001 mm/mm.

A tension test was performed on a steel
specimen having an original diameter of 12.5 mm and
gauge length of 50 mm. The data is listed in the table. Plot
the stress–strain diagram and determine approximately the
modulus of elasticity, the yield stress, the ultimate stress,
and the rupture stress. Use a scale of 25 mm = 140 MPa
and 25 mm = 0.05 mm/mm. Redraw the elastic region,
using the same stress scale but a strain scale of 25 mm =
0.001 mm/mm.
