Now what we see is what would actually happen to our system if it were driven by a very low frequency source. In effect the forcing function acts like it had two states, call them push and pull. With the first push, the strip is forced down and responds by vibrating about its pushed position with a high frequency oscillation characteristic of its restoring force and mass. Then the forcing function hits its other half cycle and pulls, the strip flops up to its pulled position and vibrates about that point for a while. See if you can see the action I have described. You might try the Phase Space Orbit view at a 90 degree pitch angle.
To exaggerate this effect lets cut the angular frequency in half again to 0.05 and double the number of chronons per cycle at the same time. Then run the model again. Here you can begin to see the vibratory motion associated with the transient that occurs when the force goes from push to pull, begins to decay visibly in the time of the half orbit. This is because we still have the energy loss coefficient greater than zero. To exaggerate this effect increase the energy loss coefficient to 0.1 and run the model again.
