=+Show that if such a damping model is used even for large modal damping ratios (which then might not be an accurate representation of reality), the modes of the undamped system are still equal to the modes of the damped one, but that the eigenvalues of the damped system are related to the nondamped frequencies by:

????s = −????sω0s ± iω0s

√

1 − ????2 s
