Gyroscopic effect is the effect that helps to maintain the orientation of a rotating body. Gyroscopes are devices that make use of the gyroscopic effect. A very good example of gyroscope is a bicycle wheel. Take a look at the following video to clearly understand gyroscopic effect:
I am not able to understand about this gyroscopic effect.I have lot of confusions about this like, why gyroscopic effect acts only on a rotating body?How it help’s to maintain orientation of rotating body?
The orientation of a rotating body changes only when an external torque acts on it. In a gyroscope, the angular momentum of the spinning disc and gimbals (if any) minimize the external torque acting on the disc. This is the reason why, the spinning disc is able to maintain the orientation in three-dimensional space.
Angular momentum is simply the amount of rotation an object has, taking its mass and shape into account. It is the product of moment of inertia and angular velocity of the rotating body.
