Origin of gyroscopegyro- + -scope
- an apparatus composed of a wheel which spins inside of a frame (gimbal) and causes the balancing of the frame in any direction or position. In the form of a gyroscopic stabilizer, used to help keep aircraft and ships steady.
gyro- + -scope, from French coined in 1856 by physicist Leon Foucault, from Ancient Greek γῦρος (guros, “circle”) and σκοπός (skopos, “watcher”).
gyroscope - Computer Definition
A device used to maintain orientation with the earth. It is used in airplane and vehicle navigation systems as well as game controls such as the Wii from Nintendo. Smartphone and tablet gyroscopes detect changes in orientation from portrait to landscape. A gyroscope contains three different-size rotating rings (gimbals) connected to each other at two points with the smaller, inner ring rotating around a spinning disc. While the speed of the spinning disc maintains its direction, the rings are free to move on their axes, and their movements are measured. For miniature solid state gyroscopes, see Coriolis vibrating gyroscope. Gyroscope Vs. Accelerometer A gyroscope is used to establish the relationship of the device to the earth, whereas an "accelerometer" is used to measure the change of velocity in any direction. See accelerometer.
- For his demonstration in 1851 of the diurnal motion of the earth by the rotation of the plane of oscillation of a freely suspended, long and heavy pendulum exhibited by him at the Pantheon in Paris, and again in the following year by means of his invention the gyroscope, he received the Copley medal of the Royal Society in 1855, and in the same year he was made physical assistant in the imperial observatory at Paris.
- In the case of the flywheel of a gyroscope if we neglect the friction at the bearings.
- Thus in the gyroscope the flywheel (represented by the globe in fig.
- This matter can be strikingly illustrated with an ordinary gyroscope, e.g.
