Q1/ A shaft rotating at 120 r.p.m is supported in bearing A and B, 1.8 m apart, A being at the left - hand end. Two unbalanced rotating masses of 7.5 kg and 10 kg at radii of 75 mm and 50 mm respectively are situated between A and B at distances of 0.6 m and 0.9 m respectively from A. The angle between the radii is 60" when viewed along the shaft. Answer the following questions: 1- The dynamic forces are. 2- Forces on bearings A and B due to dead weight are. 3- Resultant force at A and B are . . and 4- A rotor supported at A and B carries two masses. The rotor is (a) dynamically balanced (b) statically balanced (c) both (a)&(b) (d) none. , and . and
