In rotor system three unbalanced masses m1 = 1.2 kg m2 = 1.8 kg and m3 = 2.4 kg. The radius and angular positions of these masses from the horizontal plane are R1 = 1.135 m at 113.4° R2 = 0.822 m at 48.8° and R3 = 1.04 m at 251.4°. Two balancing masses of mA and mB are on left and right ends of the rotor respectively. The distances of unbalanced masses and right side balance mass from the left end unbalance mass mA are l1 = 0.854 m l2 = 1.701 m l3 = 2.396 m and lB = 3.097 m. Find the mass radius product and angular locations of balancing mass mA and mB for dynamic balance of the rotor system.
