The turbine rotor in the power plant of a ship as shown in Fig. 3 has a weight of 12.75 kN with centre of gravity at G and has a radius of gyration 200 mm. The rotor is mounted in bearings A and B with its axis in the horizontal fore-and-aft direction. The rotor turns at 5000 rpm anticlockwise when viewed from the stern. Determine the vertical components of the bearing reactions at A and B if the ship is making a turn to port (left) of 400 m radius at a speed of 35 km/hr.
