Critical speed
In solid mechanics in the field of rotordynamics the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object such as a shaft propeller leadscrew or gear As the speed of rotation approaches the object's natural frequency the object begins to resonate which dramatically increases system vibration
