Hi,
First of all, this is not my expertise so I'm sorry for things that are noted wrong. I would like to know some things about a zipline I'm going to build.
Here is a picture for clarification:

I could find things about ziplines, speeds and forces, but not including friction, not-moving or moving objects.
I really appreciate the help. And I want to let you know, I'm going to build a webbased calculator after this to help others as well.

First of all, this is not my expertise so I'm sorry for things that are noted wrong. I would like to know some things about a zipline I'm going to build.
- Velocity of a person after 60 and 74 meters
- Forces on the anchor points
- (wind) Forces on the building
- Forces on the ankerpoints when someone needs to be rescued.

I could find things about ziplines, speeds and forces, but not including friction, not-moving or moving objects.
- No persons heavier than 100 kg are allowed
- Rescue situation: 100 kg victim + 80 kg rescuer, hanging still in the middle
- rope used: Polyester (for friction coefficient, model: Black Marlow rappeling rope)
- pulley: steel (mode: petzl speed)
- friction must be included
- The zipline is tensioned by 'haulers' max force: 300 kg
- I'd appreciate some formulas + explanation, so I can help others as well.
