There are existing systems using the 1.75" x 1/8" mild steel tubing. I wanted to make it out of aluminum in an effort to save weight and avoid corrosion, but I wasn't sure what size aluminum support would be up to the task. Thanks for all your help! It looks like the 2x2x1/8&quot...

Thank you for the quick response. Assuming the ends are fixed do these calculations look correct? --------------------------------- 1.75" x 1/8" mild steel round tubing Yield strength = 36,000psi Section modulus = .24172 in^3 36000psi = (P * 38in / 8) / .24172 in^3 P = 1831.98lbs...

I'd like to evaluate three supports to see what sort of load they can handle. Basically they are all 48" long with 4 bolts, one at each end and one 5" from each end, with a load hanging in the center. I'm not worried about the bolts as I can make them plenty strong enough, but I'd...
