Thermal Stress Calculator

Calculate the thermal stress on a rod fixed at both ends using: $$ \sigma = E\, \alpha\, \Delta T $$

* Ensure all units are consistent: E in Pa, α in 1/K, and ΔT in K.

Step 1: Enter Input Parameters

Young’s Modulus, $E$ (Pa):

e.g., 210×10⁹ Pa (for steel)

Coefficient of Linear Expansion, $\alpha$ (1/K):

e.g., 1.2×10⁻⁵ 1/K

Temperature Change, $\Delta T$ (K):

e.g., 50 K
