How to read these records
Validation compares a defined, idealized input case with a known analytical result. A matched result confirms behavior for that case only; it does not expand the calculator's scope or replace project-specific verification.
| Case | Reference | Expected result | Status |
|---|---|---|---|
| Simply supported center point load | Closed-form equilibrium | RA = RB = P/2; Mmax = PL/4 | Matched within display rounding |
| Cantilever full-span uniform load | Closed-form equilibrium | V = wL; Mfixed = wL²/2 | Matched within display rounding |
| Plane stress transformation | Hand-calculation Mohr's circle relations | Principal stresses and maximum shear | Checked against governing relations |
| Composite centroid | Area-weighted centroid method | x̄ = ΣAx/ΣA; ȳ = ΣAy/ΣA | Checked against governing relations |
Ongoing validation
New features should receive targeted benchmark cases before release. If you find a reproducible discrepancy, include inputs, units, expected result, and the tool URL when reporting it.
