What is the minimum size rectangle steel tube needed to lift 500 lbs with the fulcrum in the middle of a seven foot tube? Assume a minimum of 1.5 inches outside dimensions, long side vertical. E.g: 2.5X 1.5.
Thank you.

Seems like a hobby project to me. We seem to get a lot of questions about the strength of materials that are rarely answered well. Might not have the right audience on the site to answer those.
Engineering would probably be a better home, but I don't want to migrate it if it's actually a home improvement thing, just one that I've never encountered before.
A bit late on the discussion, but I feel like we could simply remove the word "Romex" altogether, and substitute "nonmetallic sheathed cable", "Type NM cable", "NM cable" or similar. Correcting romex to "Romex®", seems too much like advertising to me.
When people say "romex", they mean "Type NM cable". They just don't know any better.
