The turbine rotor of a ship has a mass of 3500 kg. It has a radius of gyration of 0.45 m and a speed of 3000 r.p.m. clockwise when looking from stern. Determine the gyroscopic couple upon the ship when the ship is pitching in a simple harmonic motion, the bow falling with its maximum velocity. The period of pitching is 40 seconds and the total angular displacement between the two extreme positions of pitching is 12 degrees.

Gyroscopic Couple and Precessional Motion topics include: Precessional angular motion, gyroscopic couple, effect of gyroscopic couple on aeroplane and naval ship, stability of four wheel and two wheel while taking turns, gyroscopic couple effects. A gyroscopic couple is a force that causes a rotating object to tilt perpendicularly. Precessional motion is the movement that results when an object's axis of rotation changes direction without any external torque applied.  A gyroscopic couple is also known as gyroscopic torque. It's the torque or turning force created by a spinning gyroscope... Show more
