What is gyroscope?is it voilates the euqilibrium laws?
A gyroscope is a device for measuring or maintaining orientation, based on the principle of conservation of angular momentum. The essence of the device is a spinning wheel on an axle. The device, once spinning, tends to resist changes to its orientation due to the angular momentum of the wheel. In physics this phenomenon is also known as gyroscopic inertia or rigidity in space. The gyroscope effect was discovered in 1817 by Johann Bohnenberger and invented and named in 1852 by Léon Foucault for an experiment involving the rotation of the Earth. Foucault’s experiment to see (skopeein, to see) the Earth’s rotation (gyros, circle or rotation) was unsuccessful due to friction, which effectively limited each trial to 8 to 10 minutes, too short a time to observe significant movement. In the 1860s, however, electric motors made the concept feasible, leading to the first prototype gyrocompasses; the first functional marine gyrocompass was developed between 1905 and 1908 by German inventor Herm
