Need help to bindings...

[Szezar]

Hi guys! Do you have an idea how to do a physics simulation where I bind some rigid body objects with ropes? I would like to make electric poles. In this simulation the cables join the colums until the kinetic energy of movement like an earthquake breaks bindings. I tried everything which was comes to my mind, but I couldn't find the solution. Is it possible at all? 

Thanks in advance!
