Question
The moment of inertia of a pair of locomotive driving wheels with the axle
is 150 kg.m². The distance between the wheel centres is 1.2 m and the
diameter of the wheel treads is 2m. Due to defective ballasting one wheel
falls by 5 mm and raises again in a total time of 0.2 seconds while the
locomotive travels on a level track at 100 kmph. Assuming that the
displacement of the wheel takes place with simple harmonic motion about
mid point of total fall. Determine the gyroscopic couple produced.
Hint: Consider this motion as pitching motion in ship.
