WHIRLING OF SHAFTS AND CRITICAL SPEED
TecQuipment’s Whirling of Shafts and Critical Speed apparatus (TM1001) shows how shafts vibrate transversely and ‘whirl’ at a certain rotation frequency This helps engineers understand possible problems with long shafts and allow for them in their designs The equipment is in two parts and fits on a bench or desktopa loaded shaft on which the pulleys are placed in such positions that they rotatewhen the shaft is whirlingin planes perpendicular to the original alignment of the shaft Wth pulleys placed in any other positions, when the saft is whirling, there is a righting moment, tending to straighten the shaft, which does not exist when itOn the Whirling and Vibration of ShaftsThis critical (whirling speed) is dependent on the shaft dimensions, the shaft material and the shaft loads The critical speed is the same as the frequency of traverse vibrations The centrifugal force on the shaft = m ω 2 (y + e) and the inward pull exerted by the shaft = y (48EI / L 3 )(PDF) Critical (Whirling) Speed Of Shafts jose de jesus

A practical review of rotating machinery critical speeds
Engineers have been designing machines with long, flexible shafts and dealing with consequential vibration problems, caused by shaft imbalance since the beginning of the industrial revolution in WHIRLING OF ROTATING SHAFTS: If the rotating speed of a shaft or rotor is slowly increases from zero, it is found that at some speed, its deflection suddenly increases and it rotates in a bent state about the axis of the supporting bearings This is known as the first whirling speed of a rotating shaftMechanical Pandit ( Spreading the knowledge): Mechanical Critical speed depends upon the magnitude and location of the shaft unbalance, the length of the shaft, its diameter, and the kind of bearing support Many practical applications suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed; however, there are cases that require speeds above the critical Critical speed Wikipedia
