When the pitching of a ship is upward, the effect of gyroscopic couple acting on it will be

A to move the ship towards port side
B to move the ship towards star-board
C to raise the bow and lower the stern
D to raise the stern and lower the bow

Correct Answer: to move the ship towards star-board

The effect of the gyroscopic couple is always given on specific position of the axis of spin i.e. whether it is pitching downwards or upwards. The pitching of a ship produces forces on the bearings which act horizontally and perpendicular to the motion of the ship.
