The figure shows an arrangement of a heavy propeller shaft in a ship. The conmined polar mass moment of inertia of the propeller and the shaft is
100kg.m2. The propeller rotates at
ω=12 rad/s. The waves acting on the ship hull induces a rolling motion as shown in the figure with an angular velocity of 5 rad/s. The gyroscopic moment generated on the shaft due to the motion described is
