[TowerTalk] Calculating Forces for Tilting tower

[n8de at thepoint.net]

The tower will have its mass concentrated at the 20' level, and the 50  
lbs 'at the top' will have its mass concentrated at the 40'+ level.
if the 'hinge' is at ground level and your winch is at the 10' level,  
the total force of those two loads will be:
2x the tower load PLUS
4x the 'top' load.
that's quite a bit for the position of the winch .. AND .. if the  
winch is connected to the garage, it just might pull the garage wall  
down.

> I can attach a winch to an extra guy bracket I have at the ten foot level.

> There will be roughly 50 lbs at the top of the tower.  (Rotator, Hex
