Aug 25, 2016 at 6:29 comment added Zlelik Thanks for your comment. But I need numbers or formula? How many time hollow pipe will be better than cylinder? May be there is well know formula for this? Or you mean it will be better from point of view of stability from wind and etc, but pure compressive strength will be the same?
