Now for another "dumb question", what about the Philystran type of guying
material. Any data on contraction or expansion? Also, given the variation
in tension with the temperature what should I do? Should the guys be
retensioned based on a change if temperature? If yes, how big a change in
temp before doing this? I for one don't relish the though of retensioning
the guys on two 120+ foot towers when it is 10 below.
Hey, don't forget to light your tower tonight. You wouldn't want a jolly
old fat man, a loaded sled, and 8 reindeer doing an emperical test of what
happens when an irresistable force (Santa and crew) meets an immoveable
object (your tower)!
