Make a bendable structure beam

[Chromartha]

Hello everyone.
I’m trying to make some physic simulation but got stucked by skeletal meshes
Like the picture below, I want to make a beam that can be bended with other object put on it.

So I try to make a skeletal meshes like some common rope on Youtube like this one
But after I try to add bones in a box like this

And it just float there with no transform

Could anyone tell me other method or what did I do wrong?

I’d probably try to do it with splines instead of skeletal meshes.
