[TowerTalk] Tower wind loads

[Bob Gates]

Sorry for the elementary question, but my knowledge of civil engineering went
right out of my brain the day I left my last class approximately two life times
ago.  If you have a tower rated to hold 30sf of antenna at 70 mph, and 10sf at
90mph, what correlation, if any, can you draw about the load handling ability at
80mph.  Is there a linear relationship, or does it require a whole new set of
calcs?
Thanks in advance,
