The equipment is used for various controls in high technology vehicles. For minimizing rolling yawing and pitching of ship or air craft Gyroscope is used. Balloons use gyroscope for controlling direction, Gyroscope has application in space craft, space platforms. Thus study of Gyroscope is of high importance for any engineering student. The motorized Gyroscope consists of a disc rotor mounted on a horizontal shaft rotating in the ball bearings of one frame. The rotor shaft is coupled to a motor mounted on a trunion frame having bearings in a yoke frame which is free to rotate about vertical axis. Thus the disc can be rotated about three perpendicular axes. Angular scale and pointer fitted to frame helps to measure precision rate.
