Abstract
Any machine having a rotor Is usually considered to be,
In some degree, unbalanced. Therefore there will be a speed
(or speeds) at which resonance will occur due to the frequency
of the periodic force of the unbalanced rotor coinciding with
the natural frequencies of the system concerned, such speeds
are termed resonant or critical speeds. The mountings of most
machines are flexible In some measure. Even If the Immediate
foundation be considered absolutely rigid either the building
or the ground upon which It rests may possess flexibility.
