# Solution to Problem 271 Thermal Stress

Infinitesimal

Hello po. I have a question.

the one in your solution po,,, specifically the deformation analysis part.

Isn't it that $\delta_{T(st)} + \delta_{st}$ means that the steel shrank due to decrease in temperature?

And since, using your analysis po that is by adding the thermal expansion and axial deformation, (which is, I think, means that the temperature dropped), it resulted to a negative change in temperature. Isn't it that the temperature should've increased?
