Obi Rope cannot currently simulate these. They are typically referred to as "rods" in simulation jargon, and are very different from ropes/cables: in addition to having stretch/bend elastic potentials, they also require the computation of twist/shear. This is usually accomplished by constraining the Darboux vector, which requires particles in the rope to hold orientation information (quaternions) instead of being just positions in space.
In layman's terms: Rods are aware of twisting motion and have certain plastic behavior, so they can "remember" their original shape, but somewhat keep a new one if you force them to (think old telephone cables, the curly ones). Ropes are not.
We are working on integrating the following paper, so this is likely to be supported in the future:

Hi, Is this supported now?
I need just something that can behave as a simple wire.... from 1 inch to like 10 inches longs.... that I can bend in VR ... would be used to connect some pieces together, like electrical boards. hmm
