Gyroscope

  1. 1. :-
  2. 2. Contents  Gyroscope  History of Gyroscopes  Principle of Gyroscopes  Applications of Gyroscopes
  3. 3. Gyroscope DEFINITION : A gyroscope is a device for measuring or maintaining orientation, based on the principles of conservation of angular momentum.
  4. 4. History of Gyroscopes  1817. Johann Bohnenberger created the first know gyroscope, calling it simply the “machine”.  1820. Pierre-Simon Laplace recommended the “machine” be used as a teaching aide.  1852. Leon Foucault coins the name “gyroscope” when he uses Bohnenberger’s “machine” in an experiment involving the earth’s rotation.  1905 – 1908. The first gyroscope for marine navigation was developed by German inventor Hermann Anschutz- Kaempfe.
  5. 5.  1917. The “Chandler gyroscope” toy was invented by the Chandler Company in India. It is still considered a classic American toy.  During World War II, the gyroscope became the prime component for aircraft and anti-aircraft gun sights.  1991. Charles Stark Draper Laboratory demonstrated one of the first MEMS or “Vibratory” gyroscopes fabricated in silicon.
  6. 6. Principle of Gyroscope : Whenever a body is rotating in a plane(plane YZ) about an axis(axis Ox) and a couple is applied on the rotating body across the axis of rotation or spin in an another perpendicular plane(plane XY), the rotating or spinning body starts processing in a third mutually perpendicular plane(plane XZ).
  7. 7. Applications of Gyroscopes A. In Aeronautics :- 1. Remote control flying devices, helicopters, some hovercraft, some planes, etc. rely on gyroscopes to prevent them from flipping over or going into a spin.
  8. 8. 2. Spacecraft rely on gyroscopes for orientation while in space. 3. Aircraft and aircraft autopilots rely on gyroscopes to account for changes in direction & altitude
  9. 9. B. In Naval field 1. Gyroscope are used in ships to maintain stability as the effect of gyroscopic couple is on:- (a.) Steering (b.) Pitching (c.) Rolling
  10. 10. C. In automobiles 1. Gyroscopic behaviour is used in the racing car industry. This is because car engines act just like big gyroscopes. Because of the gyroscopic forces from the engine depending on whether the engine is spinning clockwise or anti-clockwise the cars nose will be forced up or down.
  11. 11. 2. Wheels on motorbikes act as gyroscopes and make the bike easier to balance (stay up right) when moving.
  12. 12. D. In electronics and gadgets 1. Gyroscopes are used in various fields nowadays such as in smartphones, video game controllers, computer mouses and presentation mouses.
