Position of a floating pulley

Hi,

I am studying the behaviour of a pulley that is attached to a sling. The situation looks like this:

https://github.com/jeroenstaps/Floating_Pulley

There is a drum that can give or take cable. Then there is a floating pulley with a cable through it. The pulley can move on the circle with a radius the same as the length of the sling. At the end of the cable a load is attached.

The following parameters are known:
- location of the drum
- length of the sling
- weight of the load (so you also know the gravity working on the system)
- location of the fixed point at the sling
- % friction in the pulley

The question is how the position of the floating pulley changes when a certain force is acting on the cable at the drum.

Anyone an idea on how to solve this problem?

Many views, no responses. It could be because the link shows
no "situation." Or perhaps this is GITHUB spam?

It is my github and on the github is an image that shows the situation. The link works for me.

Looking again, I see no image nor do any "highlighted" words lead to one.
There is a "sign-up" offer - no thanks. No offense intended. I am unable
to locate, to see the "situation."

Good luck
