Thermal stress (σ) = αEΔT
The stress induced is compressive in nature as a compressive force is exerted by the supports which prevent increase in length due to increase is temperature.

A cross-sectional area of 0.02 m^2 is subjected to a tensile force of 100 kN. The stress on the rod can be calculated using the formula:
Stress = Force / Area
Plugging in the values:
Stress = 100 kN / 0.02 m^2
Converting kN to N:
Stress = 100,000 N / 0.02 m^2
Stress = 5,000,000 N/m^2
The stress on the rod is 5,000,000 N/m^2.
