I got this picture from a superconducting parametric amplifier text I was reading.

(The picture is a mechanical analog of a non-degenerate parametric amplifier.)

If the balls(red and blue) were oscillating at their own natural frequencies, and an external force is driven(purple), how would the balls' frequencies be determined?

If the problem is too sophisticated, then assuming that w

_{p}= w

_{a}+ w

_{b}, then would the balls just get amplified with w

_{a}and w

_{b}conserved?

(Actually the second question is what I am interested
