Application notes Static and Dynamic Balancing of Rigid

The calculation of the maximum al­ lowable residual specific unbalance as­ sumes that the mass of the rotor is evenly distributed about the centre of gravity. If the mass of the rotor is unevenly distributed, the calculations are a little more complicated. In a perfectly balanced rotor, equal forces act on both ends of the rotor when it rotates.
