No shaft can ever be perfectly straight or perfectly balanced. When an element of mass is a distance ' ' from the axis of rotation, centrifugal force, will tend to pull the mass outward. The elastic properties of the shaft will act to restore the "straightness". If the frequency of rotation is equal to one of the resonant frequencies of the shaft, whirling will occur. In order to save the machine from failure, operation at such whirling speeds must be avoided. Whirling is a complex phenomenon that can include harmonics but we are only going to consider synchronous whirl, where the frequency of whirling is the same as the rotational speed.
"Whirling" can be either a verb or an adjective depending on context. Example: The rotor started whirling. - Verb Don't touch the whirling rotor. - Adjective
The Whirling Dervish was created in 1972-05.
The past tense of "The whirling leaves dance at her feet" is "The whirling leaves danced at her feet."
The Whirling Dervishes are an order of Sufis and Sufism is a sect of Islam. Therefore, the Whirling Dervishes are both Sufi and Islamic.
The whirling leaves danced at her feet.
Well, whirling isn't but i think whirl probably is :)

Someone can watch Whirling Dervish in Instanbul, as well as in Konya. The Whirling Dervish can be witnessed by anyone, but one must remember that this is actually a religious ceremony.
yes it is
