I am working on designing a trailer that will hold a load of 350lbs on 2 centered posts. It needs to have a safety factor of 3, so 1050lbs plus trailer weight. I am trying to determine the size of Steel square tube I must use. Any advice on formulas or methods of determining this? I would greatly appreciate it.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks
