algorithmic modeling for Rhino

Kangaroo 1 - Wood and Twine Physics Simulation - Physics Objects

I have produced the following model as a physics simulation of a real physical model (image attached), and I am trying to make it more accurate. The real model consists of a length of twine fixed at two points. 5 lengths of twine attach 5 pieces of wood to this, and their placement affects the form of the whole, as everything is connected.

The below file has the 6 pieces of twine acting as catenaries - they are divided, are strings,  and I have placed unitary forces acting down upon the division points of each. If you enable the simulation the 6 pieces of twine hang, as in real life.

In this model the 5 pieces of twine attached to the 5 'wood geometries' act as lines dependent on this relationship, ie if you move the 'wood' (these are internalised from 3d shapes from Rhino), the length of the string will change accordingly. 

With the real world model, if you move the wood the twine becomes more or less taut, as everything is connected, the wood has mass, and the pieces of twine have fixed lengths. I am interested in developing the model to replicate this. Does anyone have any ideas on how to achieve this?

I am thinking I would need to re-define the 5 pieces of wood first in grasshopper, and then include them as physics objects in the model, and geometries. I am wondering if it is possible to fix or lock the length of the twine, but enable its direction to change if the 'wood geometries' are moved? Thank you.
