Course code MEE312The turbine rotor of a ship has a mass of 50000 kg, a radius of gyration of 0.8 m, and rotates at2800 rev/min in clockwise direction when viewed from top of the ship. The ship pitches througha total angle of 170, 8½0, 8½0 below the horizontal, the motion being simple harmonic and havingperiod of 12 seconds. Determine the maximum gyroscopic couple holding-down the bolts on theturbine.
