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.
