Stress versus rupture life data for a superalloy is listed below. The stresses are given in MPa and rupture life is given in hours.

A. Make a plot of stress (log scale) versus PLM, where PLM = (T )(C + log10t).

T: is the temperature in kelvin, t: is in hours, and C = 20.

B. Predict from that plot what stress would cause rupture in 100,000 h at 450°C.
