Hey Lee I will be using braided line for the test as its smaller & HAS NO STRETCH.

 


Braided Nylon WILL stretch.

A quick search indicates that braided nylon has a modulus of elasticity (a.k.a. Young's modulus) of about 0.8 x 10^6.  You can cacluate the stretch with:

 

   Change in length = ( force * orginal_cable_length) / ( cross_section_area * modulus)

 

To get a sag of only 1" I think you will need a force much greater than 200 pouds. Perhaps over 10000 pounds for a mile long wire. It depends on the cross sectional area and the length.
