This document discusses balancing a single disturbing mass (m1) attached to a rotating shaft with a single balancing mass (m2) in the same plane of rotation. It explains that the centrifugal force of m1 produces a bending moment on the shaft, and that m2 can be attached such that the centrifugal forces of m1 and m2 are equal and opposite to counteract the effect.
