I am working with mild steel 1/16" wall tubing. I am sleeving this over another tube to extend it. The attachment point is 12" past the end of the sleeved tube. How much weight can the extention tube handle before it would bend?
What are the diameters of the tubing?
Mild steel is a pretty vague material spec. What material is this tubing actually fabricated from?
How long are both tubes?
What sort of load is going to be put on the extension? Point load, distributed load, moment, what?
How is the first tube supported?
