Picture a game of hangman. You have a vertical pole, a horizontal bar extending out from the pole and then the poor guy being slowing hanged hanging at the end of the horizontal bar. I'm trying to calculate much weight the pole can support before it bends.(adsbygoogle = window.adsbygoogle || []).push({});

Well, actually I'm trying to hang a TV on the horizontal bar, and I need to know how to size the a piece of steel for the "vertical pole" to support the TV so it won't bend.

It should be a fairly simple statics problem. But it's been 20 years since my statics class.

TV is 22 lbs and the horzontal bar is 2 ft long. The vertical pole is 18" high. I beleive that gives me a force of 66lbs that is being extered on the "vertical pole" were it is ancored at the bottom.

Is that correct? How do I think figure out the size steel that will resist bending given this force?

Any help is appreciated.
