Three mass particles are rigidly attached to the shaft, which is rotating with a constant angular velocity ω = 350kˆ rev/min. Determine the magnitudes and orientations of the reaction forces at the bearings A and B. Then, determine the correcting masses that must be removed in the correction planes 1 and 2 to dynamically balance the system if the radial distances of the correcting masses are specified as RC1 = RC2 = 3 in.
