An unbalanced system with masses m = Fig. 2. a) Calculate the mass and location of the masses that need to be placed at planes A and B to dynamically balance the system if, r=4 cm, 7 = 2.3 cm, r = 3.3 cm, L = 10 cm, L = 16 cm, L = 18 cm, and L3= 25 cm. Py Predict what are the changes need to be done on mass me if I is reduced. Justify your answer. 1.6 kg. m = 5 kg and m, 2.4 kg is shown m Fig. 2 BO 70 m, 20
