The mass of a turbine rotor of a ship is 8 tonnes and has a radius of gyration 0.6 m. It rotates at 1800 rp.m. clockwise when looking from the stem. Determine the gyroscopic effects in the following 8. cases: 1. If the ship travelling at 100 km/h strees to the left in a curve of 75 m radius, 2. If the ship is pitching and the bow is descending with maximum velocity. The pitching is simple harmonic, the periodic time being 20 seconds and the total angular movement between the extreme positions is 10°, and 3. If the ship is rolling and at a certain instant has an angular velocity of 0.03 rad/s clockwise when looking from stern.

r.p.m. clockwise when looking from the stem. Determine the gyroscopic effects in the following
8.
cases:
1. If the ship travelling at 100 km/h strees to the left in a curve of 75 m radius, 2. If the ship is pitching
and the bow is descending with maximum velocity. The pitching is simple harmonic, the periodic time
being 20 seconds and the total angular movement between the extreme positions is 10°, and 3. If the
ship is rolling and at a certain instant has an angular velocity of 0.03 rad/s clockwise when looking
from stern.
