Main Question or Discussion Point
Can anyone please help me with a question re the minimum size square steel pipe needed to bear a load. I loved physics but never took mechanical engineering. I am rigging a winch to one end of a pipe to lift a static load (holding up a gangway temporarily to repair). The gangway weighs around 500 lbs., and will be supported in the middle (essentially all of the weight). The proposed pipe is mild steel, 2.5 inch square, 12 feet long, 1/8 inch wall thickness, and connected at the other end and in the middle to supports. In essence, would the pipe bend if holding that load at 6 feet out from the support? What size pipe would bear the load? Thanks!!!
