Unformatted text preview: , one from zero to about 0.02 in/in and the other from zero to maximum strain. From this diagram find the modulus of elasticity, the yield strength (0.2 percent offset ), the ultimate strength, and percent reduction in the area. 10. Compute the true stress and the logarithmic strain using the data of Prob. 9 and plot the results on log-log scale. Then find the plastic strength coefficient and the strength-strengthen exponent m. Find also the yield strength and ultimate strength after the specimen has had 20 percent cold work....
