These time histories correspond to damping ratios of 0, 0.1 and 0.5. (Recall that for oscillations to exist in the free reponse, the damping ratio must be less than one.) The most obvious influence of ...

The whole Earth oscillations, or tones, are mathematically described in such a way that we can easily "read" the damping (i.e. how loud the oscillation is) due to a specific structure and separate ...
