What are the laws of gyro-dynamics?

Gyro-dynamics is used to deal with gyroscopic motion, which is very important to create an aircraft application. In gyro-dynamics law, properties of rigidity are explained. In simple words, even if the gyroscope changes location, the axis of the spin will not change without the external force.

Laws of gyro-dynamics:

► If a rotating body is mounted and freely moves about an axis that passes through the center of mass, then the spin axis used will remain fixed in inertial space without displacing any of the frames.

► Suppose a constant torque is applied to any direction, such as an axis, or perpendicular to the axis. In that case, the spin axis will move about an axis that is mutually perpendicular to both the spin and the torque axis.
