The turbine rotor of a ship has a mass of 30,000 kg, a radius of gyration of 600 mm, androtates at 2400 rpm in a clockwise direction when viewed from aft(tail or stern of the ship).The ship pitches (moves up and down) through a total angle of 15o, 7 ½ o above and 7 ½obelow the horizontal, the motion being simple harmonic and having a period of 12 s.Fig. 1 shows a side view of the ship.Determine i) the maximum gyroscopic couple on the holding down bolts on the turbine,[186.5 kN m]ii) the direction of yaw (the turning of ship or the correct course of the ship) as thebow (front end of ship)
