This guy outlines a simple tension meter you can build it yourself for
about $.00
http://www1.foragebeef.ca/ $foragebeef/frgebeef.nsf/all/frg35/$FILE/fencetension.pdf

It's for wire and not cable in which I'm interested in but the idea is
pretty simple:

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?

Thanks,

Curbie

 Jim,


Thanks, they have a large image of their device showing mechanical
details here:

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
behind it.

Any idea on terms for keywords I should use to search for the math?

Thanks,

Curbie

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