Q$\_($c$)$ in Equation $9\mathrm{.}23$ S$-590$ alloy having the steady$-$state creep behavior shown

in animated Figure $9\mathrm{.}40.$ Use data taken at a stress level of $300$MPa$(43,500\backslash$psi $)$ and temperatures of $650\backslash$deg C and $730\backslash$deg C$.$ Assume that

the stress exponent n is independent of temperature.

$($b$)$ Estimate $\backslash$epsi $\_($s$)^()$ at $600\backslash$deg C$(873$K$)$ and $300$ MPa $.$
