Question 3 A shaft rotating at 180 rev/min is supported by bearings A and B, 2.1 m apart, A being at the left-hand end. Two unbalanced rotating masses of 8.1 kg and 10.2 kg at radii of 80 mm and 52 mm, respectively, are situated between A and B at distances of 0.63 m and 0.92 m respectively from A. The angle between the radii is 60° when viewed along the shaft. Take A as your reference plane, then, using the graphical method, determine the dynamic forces at A and B when the 8.1 kg mass is vertical and above the shaft and the 10.2 kg mass is on the right of the 8.1 kg mass when viewed from B to A.
