Sorry for the late reply, i have been away for the last few days.  I
understand your system now, the purpose of the green springs is to create
bending elasticity (they are only compressed, not expanded).  I have not
tried this technique so far, but it could be useful (although linear
elasticity would probably not be very good in this case).

This is about what i tried (i'm storing the speed of each mass so
calculating the relative speed is no problem). But math is not that
simple, especially not whan working with functions.
