Help How to find out the rope tension

[josemendez]

I need the rope, which is already hooked, not to stretch when pulling the other one, but to uncouple the hook, how do I know when to uncouple

What do you mean by "uncouple the hook"? If you mean disabling the attachment, you can do that when the strain exceeds a threshold you define. For instance if the rope is stretched by more than 30% (strain > 1.30) then you disable the attachment.
