The turbine rotor of a ship has a mass of 2.2 tonnes and rotates at 1800 rpm clockwise when viewed from the aft. The radius of gyration of the rotor is 320 mm. Determine the gyroscopic couple and its effect when the: (i) ship turns right at a radius of 250 m with a speed of 25 km/h (ii) ship pitches with the bow rising at an angular velocity of 0.8 rad/s (iii) ship rolls at an angular velocity of 0.1 rad/s.
