Question: the change in yield strength as a function of temperature...

Question details

The change in yield strength as a function of temperature is given in the same form as equation 2.13 in the textbook (posted picture). where sigma_o = yield strength at room temperature, 'a' = 1 and the melting point (Tm) of the 7075 alloy is 873 K. Calculate the maximum operating temperature of the spacecraft before the alloy will start to yield.
