3" x3" tube, 3/16' vs 1/8" thick load strength
Hello,
Any help would be appreciated. After calling umpteen places, and searches, I've found this site, which is a gold mine of info, and thanks for that.
I am trying to figure out what the load strength of steel tubing, that is 3" x 3" 3/16" wall (.188) compared to same 3" x 3" at 1/8" thickness.
I will be using the tubing in manufacturing trailer extensions for launching of boats/sailboats, etc, and currently use 3/16" with no problems. It's pretty heavy duty after galvanized, and have had no problems with even heavier boats, 8000 lbs (10% of weight actually on tongue) using the extensions, and was hoping to be able to use 1/8", if not for the longer ones (12" then the 7' and 9' size.
picture of how it's used at www.extendahitch.com
Boats usually only have 10% of the boat weight on the tongue, and these aren't used for towing, strictly for launching at ramps.
Just not sure of the weight a 1/8" 3 x 3 steel tube will handle.
Any help would be greatly appreciated.
Thanks
Dan
