Sloped track line and forces

[Fairfield]

Was wondering if anyone had any information they could share on finding the forces applied to each anchor (upper and lower) , while using a slopped track line. I know how to get the forces on a horizontal line, but also know they don't apply. Thanks for the help.

This is an almost impossible calcuation.

Pete Donzelli tried to come up with a formula but said that there were too many variable.

If cable/non-stretch rope is used there are formulas that sorta work. There are threads in the archives dealing with this. I'm sure someone will bring up the past threads.

Dave Spencer had a great presentation...but it got lost during a server crash.

I think that Ken has something on his page:

Found a great app for a smart device. Rigcalc, gives the answer to my question.
