Question

An aeroplane is making a left turn as viewed by an observer from the rear of the plane The engine rotor of the plane are running in clockwise sense when viewed from the rear side The gyroscopic effects tend to

• A. lift the nose of aeroplane
• B. dip the nose of aeroplane
• C. lift the tail of aeroplane
• D. have no effect on aeroplane

Hint:

In gyroscopic systems precession causes a force at a right angle to the input force which in this case results in the plane’s nose dipping when turning left

Answer 1

The Correct Option is B

When the plane makes a left turn and the engine is rotating clockwise the gyroscopic effects cause the plane’s nose to dip This phenomenon is due to the gyroscopic precession that results from the engine’s rotation
