Rigidity is a property of a gyroscope defined
in the First Law of Gyrodynamics.
If a rotating body is so mounted as to be completely free to
move about any axis through the centre of the mass, then its spin
axis remains fixed in inertial space however much the frame may
This means that even if the location of the gyroscope changes, the axis
of the spin will continue to point in the same direction relative to space
unless acted upon by an external force or torque.
It is this property that is responsible for apparent wander and transport

to make it easy for instructors to demonstrate this and other gyroscopic
principles and properties, such as:
