Yahoo Answers(steel) Feb 18, 2012Thus, you don't meet the required safety factor, and it's probably not a good idea to stand next to the pipe. On the other hand, steel is a ductile material, and it's possible that, as the load increases beyond the yield point, the load redistributes, which means stress is not linearly related to load.
Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length. Loading in the middle of the longest tube is a worst case for stress on a cage member. Square tube assumes bending with one side parallel to the load (think square vs diamond). The safety factors use the numbers in the table below for strength.(plate) Tube Calculator - Rogue Fabrication(steel) Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length.
