### Necessary and sufficient conditions for periodic motion

Let us fix a reference frame $S$ with origin in $O$ in the euclidean space $\Bbb R^3$, then let us also define a periodic motion in the following manner: A motion is periodic if and only if the time-...

### Estimate the revolutions per minute for which the engine will experience the greatest vertical vibrations

A freely rotating motor rests on a thick rubber floor to reduce vibrations (vertical oscillations). The motor, due to its weight, sinks $10$ cm into the floor. Estimate the revolutions per minute for ...
