Q.3 A Shaft carries two unbalances of magnitude 20 kg-cm and 10 kg-cm in the planes A & B respectively. Planes A and B are 40 cm apart and the relative angular setting of A and B is 900 Plane A is 55 cm to the right of left end bearing, whereas plane B is 55 cm to the left of right end bearing. A third unbalance has to be introduced at a location C, such that the shaft is statically balanced and the magnitude of the bearing reactions are minimum possible (Considering only dynamic forces). The shaft is rotating at 1200 rpm. Determine - 1. Location of C, with respect to A and B on the shaft 2. The magnitude of unbalance at C 3. Angular position of unbalance at C with respect to A & B
