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
304 Stainless Reference
| Alloy | Stainless steel 304 |
| Elastic modulus E | 193 GPa |
| Typical 0.2% proof stress | 215 MPa |
| Typical density | 8000 kg/m^3 |
| Preset support case | Simply supported beam |
| Preset loading | Uniform load |
| Preset section stiffness I | 2100 cm^4 |
Engineering Notes
- Stainless steel 304 is often selected for corrosion resistance and architectural exposure rather than minimum structural mass.
- Its elastic modulus is slightly below carbon steel, so visible deflection can still govern in slender members.
- If the profile is already known, replace the default stiffness with the exact section inertia before using the result.
