The yield stresses of several samples of a steel containing 0.12% carbon with different grain sizes were measured. The data are shown here.

Grain-Size Inverse

Sample d^(-1/2) [mm^(-1/2)] Yield Stress (MPa)

A 24 500

B 19 420

A 12 320

A 10 250

A 6 190

(a) calculate the grain size of each steel sample in micrometers.

(b) Which sample has the grain size of 27.7 micrometers?

(d) What is the grain size of the sample that has the highest yield strength?
