Difference between static and dynamic balancing of rotating masses

hi all

so what is the difference between static and dynamic balancing of rotating masses. And how what is the need for dynamic balancing?

    Hi zaveri
    Static balancing is performed with the object being balanced at rest. Dynamic balancing is performed with the object being balanced in motion.
    Static balancing is done without the part moving, dynamic is done with the part moving it is spun and using stroboscopic flash the heavy bit is higlighted and you then add or remove weighs till it stops vibrating.

    In static balancing, the rod around which mass is rotating is to be fixed whereas in dynamic balancing,the rod moves along with the rotating mass.

    so then how are the blades of a ceiling fan or any fan , balanced dynamically ? what is the procedure ?

    I think that static balancing is the balancing of a material which, is at rest, with respect to some frame of reference. Mean to say that in static balancing we prevent the material from motioning either in rotational and translational with respect to some frame of reference while in dynamic balancing if an object is moving with constant velocity with respect to some particular frame of reference then we strict the object to keep its constant velocity state

    static balance will be produced if the sum of the weights about the axis of rotation is zero...and a system is said to be in dynamic balanced when there doesnot exist any resultant centrifugal force as well as resultant couple.
