dynamic balance

[dī¦nam·ik ′bal·əns]
(mechanics)
The condition which exists in a rotating body when the axis about which it is forced to rotate, or to which reference is made, is parallel with a principal axis of inertia; no products of inertia about the center of gravity of the body exist in relation to the selected rotational axis.

dynamic balance

The balance of a rotating object such as a propeller, rotor, or high-speed wheel. If the rotating body is not balanced, vibration will occur. Weights are attached at the required locations on the rotating body to balance it.
