What is dynamic balancing?
A system is in dynamic balance when there does not exist any resultant centrifugal force and also a resultant couple.
For example Several rotating masses
When several masses rotate in different planes, the centrifugal forces in addition to being out of balance also from the couple.

When several masses rotate in different planes, the centrifugal forces in addition to being out of balance also from the couple.
As shown in the figure above the
product of mr an mrl usually have been referred to as force and couple
respectively as it is more convenient to draw force and couple polygons with
these quantities.
If
m1 and m2 are two masses revolving diametrically opposite
to each other in different planes such that m1r1 = m2r2.
The
centrifugal forces are balanced, but an unbalanced couple of magnitude m1r1l1
= m2r2l2 is introduced.
The couple acts in a plane that contains the axis of rotation and the two masses. Thus, the couple is of constant magnitude but variable direction.
