[TowerTalk] Poor mans tension guage: correction

[Chris Wendling]

Sorry for the math error in my origianl post, when I hit the send key, the light came on ;>).
  
  Doubling the tension does not double the frequency.  You need to  have 4 times the tension to double the frequency.  (There's a  square root in the equation!!)
  
  So if you calibrate your poor mans guage to 100 lbs, it will measure  400 lbs tension when the frequency is twice as high..  It's really  not as complicated as it sounds. The frequency increases with the  square root of the tension. Example: Increase the tension by 16 times,  and the frequency is increased 4 times.
  
  Of course, you could just calibrate it to 400 lbs to begin with, if you can find 400 lbs to suspend!
