Formula and methodology
Formula: Bending stress σ = Mc/I.
The elastic beam relation reports the outer-fiber stress implied by the entered moment and section geometry.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Bending moment — N·m; minimum 0; maximum 1000000000
- Outer-fiber distance — m; minimum 1.0E-6; maximum 1000000
- Second moment of area — m⁴; minimum 1.0E-24; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Bending moment | 1000 |
| Outer-fiber distance | 0.05 |
| Second moment of area | 1.0E-6 |
Bending stress = 50 MPa.
Assumptions and limits
- Inputs use SI units and second moment is positive.
- The section is in the linear-elastic bending range.
- Yielding, shear, buckling, fatigue, stress concentrations, and structural approval are not modeled.
