Homework Answers
Hi here is the solution for your question. I hope I could help you in future also. If anything is not clear to you please let me know before giving your valuable feedback.
I would like to improve that in the future.
Thanks
Solution
Here figure is not shown. So value of diameter that I have taken can be slightly different but conceptually I did it right.
i hope it will help you. If I
missed anything please let me know before giving your rating.
Thanks

An uncold-worked brass specimen of average grain size 0.008 mm has a yield strength of 151 MPa. Estimate the yield strength of this alloy (in MPa) after it has been heated to 600°C for 1220 s, if it is known that the value of ky is 11.5 MPa-mm 1/2. The Animated Figure 7.25 may be helpful.

A brass alloy is known to have a yield strength of 275 MPa (40,000 psi), a tensile strength of 380 MPa (55,000 psi), and an elastic modulus of 103 GPa (15.0×106 psi). A cylindrical specimen of this alloy 9.0 mm (0.35 in.) in diameter and 245 mm (9.65 in.) long is stressed in tension and found to elongate 9.0 mm (0.35 in.). A) What is the yield strain? B) What is the test strain?

S. (2 Marks) An alloy with an average grain diameter of 35 um has a yield strength of 163 Mpa. and when it undergoes strain hardening, the grain diameter reduces to 17 um with an increase in yield strength to 192 MPa. If the coarseness of the alloy desired for a particular application cannot exceed 12 um, what will be the expected yield strength?
