# GATE Questions & Answers of Gyroscope

## What is Gyroscope ?

Gyroscope is a mechanical device consisting of a wheel or rotor mounted so that it can spin about an axis which is free to rotate in any direction. The position of the axis is not affected by tilting of the mounting, so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.

A car is moving on a curved horizontal road of radius 100 m with a speed of 20 m/s. The rotating masses of the engine have an angular speed of 100 rad/s in clockwise direction when viewed from the front of the car. The combined moment of inertia of the rotating masses is 10 kg-$\mathrm m^2$. The magnitude of the gyroscopic moment (in N-m) is __________
