Calculation Basis
Assumptions & Limits
- Preset values speed up the setup but do not replace final section or material verification.
- The page is designed for fast deflection and reaction checks.
- Local code rules, long-term effects, and connection details still need separate review.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materials references
Example Angle Section Setup
| Profile family | Equal angle steel section |
| Example size | 100 x 100 x 10 mm angle |
| Elastic modulus E | 210 GPa |
| Preset principal inertia basis | 220 cm^4 |
| Preset support case | Simply supported beam |
| Preset loading | Centered point load |
| Use case | Preliminary angle section check |
Engineering Notes
- Angle sections are asymmetric, so deflection and stress behavior can vary significantly depending on load direction and restraint.
- This page should therefore be treated as a practical beam check around one chosen stiffness axis, not a full unsymmetric bending solver.
- If torsion, eccentric loading, or lateral instability is relevant, the default beam-style check here is not enough on its own.
