 ```I guess I didn't follow the explaination. Why would there not be a difference in torsional loading between a tower constrained only at the bottom versus one constrained at both the top and bottom?

Torsio nal loading on a triangular tower indeed does add to the down force somewhat, but this is quite small compared to the other loads. Thus, a tower which rotates inside a ring-coupled guy system is simply relieved of whatever torsion loading might otherwise be imposed upon it. It is neither stronger nor weaker as a result.Make sense?n2ea >_______________________________________________ > > > >_______________________________________________ >TowerTalk mailing list >TowerTalk@contesting.com >http://lists.contesting.com/mailman/listinfo/towertalk > > > _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
