In the system of Fig. 5.4.12, assume that m1 D 1, k1 D 50, k2 D 10, and F0 D 5 in mks units, and that ! D 10. Then find m2 so that in the resulting steady periodic oscillations, the mass m1 will remain at rest(!). Thus the effect of the second mass-and-spring pair will be to neutralize the effect of the force on the first mass. This is an example of a dynamic damper. It has an electrical analogy that some cable companies use to prevent your reception of certain cable channels.
