Introduction
A gyroscope is used to maintain equilibrium and determine orientation. A mechanical gyroscope is what we see in our everyday lives and is the most common. This type of gyroscope was first made in 1817 by a German, Johann Bohnenberger. This gyroscope is accurate to a degree and has replaced the once more common magnetic compass. The mechanical gyroscope is now used in most airplanes, helicopters, ships and other mechanisms as the primary navigation tool. But unfortunately there is a limitation to its accurateness and when it comes to measuring the minute changes in the earth’s rotation due to earth quakes (even magnitude 8) the mechanical gyroscope becomes obsolete.
