• ### Critical speed

As the speed of rotation approaches the object's natural frequency the object begins to resonate which dramatically increases system vibration. The resulting resonance occurs regardless of orientation. When the rotational speed is equal to the numerical value of the natural vibration then that speed is referred to as critical speed.
