Safe tortion load 2X2 square tubing

  1. Mar 11, 2012 #1
    I want to build a crane to load my handicap scooter on my pickup. In my design I need a 36 inch beam, fastened at one end, free at the other. The beam will be loaded at the free end with 150 pounds of static weight, and it will also have a maximum moment of 500 foot-pounds tortion at the free end. I would like to use square steel tubing for the beam. Will
    2"X2"X3/16" tubing be adequate?

    Are there tables available that list the safe tortion loads of steel tubing?
