[TowerTalk] Calculations for tramming forces

[Doug Faunt N6TQS +1-510-655-8604]

Hi all,
Is there a book, or some simple software that can calculate the forces
on the tower, the anchors and the tram cable when tramming up an
antenna?

I've seen rules of thumb for the forces on the tramline for certain
angles between the two parts of the cable at the hpist point, (but
can't locate that information now).
