The engine of an aeroplane rotates in clockwise direction when seen from the tail end and the aeroplane takes a turn to the right. The effect of gyroscopic couple on the aeroplane will be to dip the nose and raise the tail.

The steering of a ship means

The rolling of a complete ship side-ways is known as pitching of a ship.

The rotor of a ship rotates in clockwise direction when viewed from stern and the ship takes a left turn. The effect of gyroscopic couple acting on it will be

The rotor of a ship rotates in clockwise direction when viewed from stern and the ship takes a right turn. The effect of gyroscopic couple acting on it will be to raise the stern and lower the bow.

The pitching of a ship is assumed to take place with simple harmonic motion.

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

The height of a Watt’s governor (in metres) in equal to

The ratio of the height of a Porter governor (when the length of arms and links are equal) to the height of a Watt’s governor is

When the sleeve of a Porter governor moves upwards, the governor speed

A Hartnell governor is a
