A rotating shaft carries three unbalanced masses of 4 kg, 3 kg, and 2.4 kg at radial distances of 75 mm, 85 mm and 50 mm and at the angular positions of 45, 135 and 240 respectively. The planes of unbalanced masses, as well as planes of the countermasses are shown in the figure. Plane C is to be taken as the reference plane and the various distances are to be considered from this plane. Determine the amounts and locations of the counterweights at planes C and C required for complete balance. 200 225 375 75 240 135 45 2 C 3 C(RP)
