Physics Problem

Hello,
i have created a “Museum_Barrier_Rope” with physics Constraints from UE4. I have directly created it in UE4 without any other 3d software.
This “Museum_Barrier_Rope” works good now. But one great problem did i have. If i shoot with the ball directly to the Chain from this “Museum_Barrier_Rope” then the “Museum_Barrier_Rope” flies around very fast - realy not realistic.
Is there any solution for this?
Kind regards,
Andreas
