Abstract
A single degree of freedom master oscillator attached to a simple undamped N degree of freedom 'fuzzy substructure' is studied numerically and theoretically. Results are found to be in accord with the predictions of the Pierce Sparrow-Russell theory at early times; in particular, the master oscillation manifests an apparent damping. At later times, however, the damping ceases and the energy is returned from the fuzzy to the master. The precise manner in which the energy is returned, and the time taken to do this, depend on the details of the mass and frequency distribution within the fuzzy, and in particular on the distribution of spacings between the fuzzy resonances.
