How to use the Stress Calculator
- Choose stress or Young's modulus.
- Pick what to solve for.
- Enter the values and read the result.
What does this tool do?
Normal stress is force per unit area: a 10 kN pull on a 5 cm² bar creates 20 MPa of tensile stress. Comparing stress with a material's strength tells you how close it is to yielding.
Young's modulus is the ratio of stress to strain in the elastic range — about 200 GPa for steel and 69 GPa for aluminium.
Why use it?
- Stress and modulus modes.
- MPa, GPa and psi.
- Solve for any variable.
The formula
σ = F ÷ A
E = σ ÷ ε
Accuracy and limits
- For learning and quick checks. Real engineering decisions should be verified by a qualified professional.
