Hi all!(adsbygoogle = window.adsbygoogle || []).push({});

I have an odd question that i thought somebody with a degree could help with. I am looking to find the formula to describe wire sag over a given length and given horizontal tension and given wire diameter. I believe the formula is a catenary but am unsure how to apply it to my situation.

I have a .024" (inch) wire diameter.

i have a horizontal tension of 30 lbs

i have a distance between level centres of 30ft

help would be greatly appreciated.

sorry if this is in the wrong category, its my first day :P

PS: i have a chart from a website i found but the description is suspect, here is the link.
