What amplifies the effect of imbalance in a rotating system?

In a rotating system, the imbalance is magnified by factors such as speed. As the rotational speed of a system increases, the centrifugal forces acting on the imbalanced mass grow in proportion to the square of the speed. This means that even a small imbalance can translate into substantial forces at higher speeds, leading to increased vibrations and potential damage to the rotating components. The resultant forces from the imbalance can cause additional stresses on bearings, seals, and structural components, which may ultimately lead to system failure if not managed properly.

In contrast, while mass contributes to the potential for imbalance, it is the speed that intensifies the impact of that imbalance on system performance. The other factors, such as friction and lubrication, play roles in system operation but do not directly amplify the effects of imbalance in the same manner that increased speed does.
