THE MYSTERIES OF ROTATION: by a Student
Reading edition
ONE of the most fascinating results of the attention bestowed in the last few years upon gyroscopic effects, has been the almost final perfection of the gyrostat-compass, and the Scientific American Supplement contains an excellent account of it, together with one of the clearest popular explanations of its action which we have seen. The tests of the Anschütz instrument as improved by Sperry, were carried out last April for five days on a steamer plying between New York and a port in Virginia. Although the vessel rolled in heavy seas, it was found that the compass kept practically absolutely on the meridian during the whole period. The electric motor runs at 6000 revolutions per minute, and the instrument is in the steering-engine room, connected electrically with a repeating compass on the bridge. It is stated that at all ordinary latitudes this compass has a directional force some fifteen times greater than a corresponding magnetic compass. This, however, diminishes on approaching the poles. The interesting feature of the gyro-compass is that its action in pointing true north depends upon the rotation of the Earth.
