- How tube strength changes with diameter
I'm planning on making marquee poles out of aluminium tube. I did so last year and they worked well, but they flexed slightly under tension.
To correct this flex, I want to use slightly different size of aluminum tube.
I used 4" tube, with a ¼" wall, at a length of 30'.
Will the tube be stronger with a larger diameter, or do I have to go for a larger wall thickness?
Basically, is there a way of working out
strength /diameter ratio?
Or even more basically, will it be weaker or stronger with a larger diameter tube, keeping the wall thickness the same?
