The gap between the wall and the 1Omm diameter aluminum rod below is 0.6mm. If the temperature increases by 14 °C, what stress will be generated in the rod? (Hint: What temperature change will result in the rod touching the walI? What happens after that?) [E = 68.9 GPa, Coef. of Therm Exp = 24 x 10^-6 /° C] L= 1 m

Expert Solution
Step 1
Write the given information.
Write the expression of expansion of rod due to free expansion due to the change in temperature.
Understand that the gap between the wall and the aluminum rod is 0.6 mm and the free expansion due to change in temperature is 0.336 mm. Thus, there will be no stress generated in the rod.
