[Towertalk] Wind force calculations

[n6tqs@arrl.net (n6tqs@arrl.net)]

Hi people,
We've just had some big winds through here, and most people haven't
had too many problems (although one person has reported half of a 40M
element completely vanished, and I have to climb a little to realign
a beam for a friend).

But, it's got me curious- what's the formula for the sideways force in
pounds, given a wind velocity and antenna area?
