Document Summary

Sut = 470 mpa (68 kpsi), sy = 390 mpa (57 kpsi) ans. Sut = 620 mpa (90 kpsi), sy = 340 mpa (49. 5 kpsi) ans. = 1. 32 times larger than sae1020 cd ans. = 1. 15 times larger than g10500 hr ans. From table a-20, the ductilities (reduction in areas) show, The stiffness values of these materials are identical ans. 1040 q&t sy = 593 (86) mpa (kpsi) at 205: ans. 2-6 using table a-5, the speci c strengths are: Astm 30 gray cast iron has no yield strength. 2g(1 + ) = e = e 2g. Gray cast iron: = 14. 5 2(6) E 90 0. 003 30 000 kpsi ans. 2-10 to plot true vs. , the following equations are applied to the data. = 0. 1987 in2 for 0 l 0. 0028 in for l > 0. 0028 in. The results are summarized in the table below and plotted on the next page.
