This question has been bugging me for a while. I've been trying to figure out
why tower guys are preloaded. I haven't worked out why that is an advantage
over simply tightening them enough to take up the slack. I run the math on
wind loading and such and the preload always seems to increase the stress on
the tower. There must be something I am overlooking.
