Resonance and Whirling MCQ [Free PDF] Objective

Explanation:-Critical or whirling speed of a shaft. When the rotational speed of the system coincides with the natural frequency of lateral/transverse vibrations, the shaft tends to bow out with a large amplitude. This speed is termed as critical/whirling speed. Whirling speed or Critical speed of a shaft is defined as the speed at which a rotating shaft will tend to vibrate violently in
