Problem 4 The yield point of a steel that has an average grain diameter of 21.3 um is 202 MPa. At a grain diameter of 7.4 um, the yield point increases to 286 MPa. At what grain diameter will the yield point be 315 MPa?
The yield strength for an alloy that has an average grain
diameter of 5.7 × 10-2 mm is 140 MPa. At a
grain diameter of 7.3 × 10-3 mm, the yield
strength increases to 277 MPa. At what grain diameter, in mm, will
the yield strength be 228 MPa?

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?
The yield strength for an alloy that was an average grain diameter of 5.4 x 102 mm is 133 MPa. At a grain diameter of 7.4 x 10 mm, the yield strength increases to 250 MPa. At wh grain diameter, in mm, will the yield strength be 203 MPa? mm the tolerance is +/-6% Click if you would like to Show Work for this question: Open Show Work
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.

5 pts > Question 2 A Treasury bond that matures in 10 years has a yield of 4.75%. A 10-year corporate bond has a yield of 7.35%. Assume that the liquidity premium on the corporate bond is 0.6%. What is the default risk premium on the corporate bond? Round your answer to two decimal places. Your answer should be between 0.74 and 2.52, rounded to 2 decimal places, with no special characters.
