No professional advice

This site does not provide engineering sign-off, electrical code approval, fabrication certification, legal advice, or tax advice. It offers general educational calculation support only.

Where real safety, code compliance, or tolerance-sensitive production work is involved, final judgment should come from a qualified professional and the official source material.

Changing assumptions

Formulas, machining assumptions, material factors, and practical interpretations can vary by context. A result that is useful for learning may still need validation before being used in production.
