Gyroscopic Stabilization Introduction of Gyroscope (A) Axis Of Spin If a body is revolving about an axis, the latter is known as axis of spin. (B) Precession Precession means the rotation about the third axis which is perpendicular to both the axis of spin and axis of couple (C) Axis Of Precession The third axis is perpendicular to both the axis of spin and that of couple is known as axis of precessions. (D) Gyroscope It is a body while spinning about an axis is free to rotate in other directions under the action of external forces. Examples;; Locomotive, automobile and aero plane making a turn. In certain cases the gyroscopic forces are under sirable whereas in other cases the gyroscopic effect may be utilized in developing desirable. (E) Gyroscopic Effect To a body revolving (or spinning) about an axis of spin, if a couple represented by a vector OY perpendicular to axis of spin, then the body
