The block is fitted between the fixed supports. $($Figure $1)$ The coefficient of linear thermal expansion of the material is $6\mathrm{.}0({10}^{-6})(F{)}^{-1}.$

Part A

If the glued joint can resist a maximum shear stress of ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=2$ksi, determine the temperature rise that will cause the joint to fail. Take $E=10({10}^3)ksi,$

$u=0\mathrm{.}2.$

Hint: Add the thermal strain $T$ to the equations for Hooke's law.

Express your answer in degrees Fahrenheit to three significant figures.
