gyroscope report
1.0 INTRODUCTION
A gyroscope is a device for measuring or maintaining orientation. Mechanically, a gyroscope is a spinning wheel or disk in which the axle is free to assume any orientation. Although this orientation does not remain fixed, it changes in response to an external torque much less and in a different direction than it would without the large angular momentum associated with the disk’s high rate of spin and moment of inertia. The device’s orientation remains nearly fixed, regardless of the mounting platform’s motion, because mounting the device in a gimbal will minimizes the external torque. The examples of the application of gyroscope is in inertial navigation systems where magnetic compasses would not work as in the Hubble Telescope or would not precise enough as in ICBMs, or for the stabilization of flying vehicles like radio-controlled helicopters or unmanned aerial vehicles. Due to their precision, gyroscopes are also used in gyrotheodolite to maintain direction in tunnel mining. Within mechanical system or devices, a conventional gyroscope is a mechanism comprising a rotor journal to spin about one axis. The journals of the rotor being mounted in an inner gimbal ring. The inner gimbal is journal for oscillation in an outer gimbal for a total of two gimbals. The outer gimbal or ring, which is the gyroscope frame, is mounted so as to pivot about an axis in its own plane determined by the support. This outer gimbal possesses one degree of freedom and its axis possesses none. The next inner gimbal is mounted in the gyroscope frame which is outer gimbal so as to pivot about an axis in its own plane that is always perpendicular to the pivotal axis of the gyroscope frame (outer gimbal). this inner gimbal has two degree of freedom.
The axle of the spinning wheel defines the spin axis. The rotor is journal to spin about an axis, which is always perpendicular to the axis of the inner gimbal. So the rotor possesses three degrees of rotational
