A rotor is rotating with a constant angular velocity

ω = 50 rad/s, and is dynamically balanced by the two correcting masses. A decision has been made to use planes 1 and 3 instead of planes 1 and 2.

Determine the magnitudes and orientations of the new masses (mC1)new and (mC3)new at the same radii RC1 = 50 mm and RC3 = 150 mm.
