A 1400 mm long galv steel beam, size 40x20x2. 80 mm of the beam on one end is welded in flat position to a platform. How much weight can I put safely on the other end? What if instead of being flat it will be on a short side/rib? The platform is meant to spin, will this effect the weight the beam can hold at the other end?
I am not an engineer and do not understand the formulas I found in other posts. This is for a home project.
