Question

The thermal stresses developed in a rod do not depend on its__________

Answer 1

Hint The thermal stress is defined as the mechanical stress created by any change in temperature of a material. These stresses can lead to the fracturing or the plastic deformation depending on other variables of heating which include material types and constraints.

Complete step by step answer
To answer this question at first it is required for us to analyze the situation and find the exact location for the generation of the thermal stress that is developed in the rod.
The thermal stress developed in the rod does not depend upon the cross sectional area of the bar.
Now we have to mention the quantities that are present in the question.
Change of the length is given that: $\alpha \Delta Tl$
So, it mainly depends on the type of the material.
At the end we can say that thermal stresses developed in a rod do not depend on its type of the material.

Note The formula of the thermal stress is $Y(\alpha \Delta T)/{L_0}$, where the Y is Young’s modulus of the given material, $\Delta T$ is the change in the temperature, $\alpha$ is the coefficient of linear thermal expansion if the given material and ${L_0}$ is the original length of the material before the expression.
