generative modeling for Rhino
Grasshopper is not a physics simulator, you cannot use it to realistically bend a curve. What you can do is measure the length of a curve, then scale the curve so you end up with a desired length. If the curve is twice too long, scale by a factor of 0.5... etc.
Thank you to your replies.
I understanded your comment.

or in this particular example you can use catenary curve.
Thank you to your advice.
I could did it!
I used catenary curve and Number sets a same distance of two point distance.
two points set a slider, and one slider's vector sets Reverse.
So when move a slider point is near each other.
