Hi,
Believe it or not, there's also very little physics involved in this second video. It's basically a list of points, trough which a circular shape is extruded to generate a tube. That's all. The only "physics" here would be gravity, which is already built-in in Unity. There are no contacts, friction, tensional or bending constraints here, and certainly no need for a particle-based / position-based dynamics engine.
If you're new to 3D and physics, I'd advise against starting with Obi. It is quite complex, and assumes certain familiarity with basic physics concepts. If you're willing to put in the time then by all means go ahead, but in this particular case it would even be counterproductive using Obi as there's much simpler and faster alternatives to do what you're describing.
