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

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

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.
