Calculate maximum bending stress using the flexure formula σ = My/I. Verify structural members against material yield strength.
Enter the maximum bending moment acting on the section and the distance from the neutral axis to the extreme fiber (y).
Input the Moment of Inertia (I). The tool uses the flexure formula: σ = My/I to calculate the maximum normal stress in the member.
Compare the resulting stress to the yield strength of your material (e.g., 250 MPa for A36 steel) and apply a safety factor (typically 1.5 to 2.0).
