This guy outlines a simple tension meter you can build it yourself for
It's for wire and not cable in which I'm interested in but the idea is
Two wire guides 40" apart, deflect the wire with a spring scale ½
inch, multiply the scale reading by 20 to determine the amount of
tension on the wire.
I know this has no direct value with cables with 1000's of pounds of
tension (like guys), but I was wondering if anyone knows or can point
me to the math behind the idea?

Here's a commercial one. Click on the Tension Meter (long URL):

Thanks, they have a large image of their device showing mechanical
The device seems to use the same principles (math) for cables that the
device I posted uses for wire, and I'm still interested in the math
Any idea on terms for keywords I should use to search for the math?

I can't help you with the math, but you might ask on sci.physics.
