Jay,
I think you may have misunderstood her question. :)
I looked to me as though she was asking what the adjustments would net in tension.
For example:
If you started with a cable tensioned to 30lbs then tightened it 4-6/64Th's what
would the tension be? (31lbs?)
My guess is that it would be insignificant.
The aileron spec is 30lbs +/- 5lbs.
I doubt you would see a difference of 1 pound either way.
I could be wrong, it's happened before :)
Sabrina,
there is a formula for that but I haven't found it yet.
Still looking :)
I am sure the tension to turnbuckle lead is not linear.
The cable will continue to stretch until you reach the yield strength and so the
ratio is a "parabolic" curve. (if I'm using that right?)
The Curve will depend on material, diameter and class (construction; IE 6x19, 6x25,
6x32 etc.) of the wire rope.
also the length of the cable will have a lot to do with it.
The stretch is a percentage so a shorter cable will stretch less total distance
than a longer one will.
If you decide to take on that experiment and take it to cable failure, be very
careful!
I have seen cables break before and they store an amazing amount of energy!
