Driven Chain: Barrier problem

 

Damping, b=   Omega =

Seventeen balls are coupled by springs in such a way that the restoring force is proportional to the difference in height between two neighboring balls.  The left hand ball is driven and the right hand ball is impedance matched.  The mass of the small balls is one and the mass of the larger balls near the center is 4.0.  The spring constant connecting the balls is one.  The length of the entire chain is 2*pi.

Set the desired frequency and run the simulation until the steady state is reached.
