Natural frequencies are the speed (s) at which vibration occurs when a structure is acted on by an outside force. When a rotating machine spins at a speed the same as or similar to the natural frequency, the structure begins to vibrate violently. This dynamic system is operating at resonance. Loud noise and damage is observed in these situations.
