FAQ
Is this a substitute for professional engineering?
No—use it to learn and screen options; qualified review still applies for compliance and safety.
Why might my numbers disagree with standards or vendor software?
Property data, rounding, and implicit safety factors differ. Treat this as transparent reasoning—then confirm with codes, datasheets, or licensed review when decisions bind.
