The rotor of the turbine of a ship has a mass of 2400 Kg, rotates at the speed of 330 rad/s. Counterclockwise when viewed from the stern (rear end). The rotor has a radius of the gyration of 0.5 m. The ship pitches 4° above and 4° below the normal position and the bow is descending with its maximum velocity. The pitching motion SHM with a period of 30 sec. Then the gyroscopic couple when viewed from the stern?
