stress strain curve 01

The following stress-strain curve was prepared based on a tensile test of a specimen that had a circular cross-section. The gage diameter of the specimen was 0.375 inches and the gage length was 4 inches. The stress scale of the stress-strain diagram is given with the factor a = 5 ksi. Estimate:

(a) The modulus of elasticity.
(b) The ultimate strength.
(c) The yield strength (0.2% offset).
(d) The percent elongation at fracture.

(a)   $E$ =

(b)   $\sigma_{ult}$ =

(c)   $\sigma_{y_{.002}}$ =

be sure to include units with the answers above

(d)   percent elongation = %
