PPT-GYROSCOPE

AN OVERVIEW Gyroscope WHAT IS A GYROSCOPE DEFINITION A gyroscope is a device for measuring or maintaining orientation based on the principles of conservation of angular momentum A mechanical gyroscope is essentially a spinning wheel or disk whose axle is free to take any orientation This orientation changes much less in response to a given external torque than it would without the large angular momentum associated with the gyroscopes high rate of spin. Abstract We show that the MEMS gyroscopes found on mod ern smart phones are suf64257ciently sensitive to measure acoustic signals in the vicinity of the phone The re sulting signals contain only very lowfrequency infor mation 200Hz Nevertheless we Ali .

Precession is a motion exhibited by rotating objects which change their angular momentum when subjected to torques, in accordance with Newton’s Second Law, and whether you realize it or not, torques and angular momentum have an impact on your everyday life. If you rode your bike today, the angular momentum of the wheels helped you maintain your balance.. Pengfei. Zhou*, Mo Li. Nanyang. Technological University. Guobin. (Jacky) Shen. Microsoft Research.
