How Can I determine if.....

I shall appologise in advance if I am missing the point...but

Do you really need CAD to answer this?

What about engineering feel, and experience?

More pertinently, what are the hinges screwed to and with what length screws?

Experience and gut feel says...

YES ...easilly if the surround is good sound timber or something better and you use decent screws..say 1 1/4" steel.

If you use 1/4" bress screw to attach it tp plasterboard the the answer is NO.

Great answer! I manage a group of design engineers and have heard lots. There seems to be a recent trend to rely on these programs rather "common sense" for the easy questions. My preference is for engineers with a little common sense that can back it up with well executed FEA analysis, if needed. Then again these programs aren't always the cat's meow and suffer from GIGO "garbage - in garbage out" or maybe in this situation verify the strength of the hinges with 2 hours of wasted work on FEA then hang the door on gypsum board.

Use deductive Logic thus:

Rig up a 12"x1"x3' timber plank with 2 of your hinges on a rigid vertical strong timber post.

Hang/Jump your own body from hinged board.

If neither You nor Board nor your hinges give --your HINGES CAN DO.

Seek the manufactures load specs. of the hinges to find the load handling capabilities.

Too many variables in hinge just to state plate size. Like plate thickness, pin diameter, composition of the brass.
