[TowerTalk] Tower Torque

[Wilson Lamb <infomet@embarqmail.com>]

Torque will be induced in a tower if wind blows from a direction not parallel 
to a guyline.
As the tower leans, it will cause differential changes of guy tension, which 
will twist the tower.
I have no idea of magnitude, but can imagine hundreds of foot pounds easily.  
Obviously a beam with asymmetric drag could be a significant contributor!
