A rigid body rotates about a fixed point O.
A moving frame is attached to the body as it rotates about the inertial frame.
A Cartesian coordinate system attached to the body has the origin at O.
On board devices indicate that the angular acceleration and angular velocity are not 0.0.
To locate a particle, commence with two assumptions:
A black arrow (scaled up by a pre-set factor to enable visualization) represents the time-evolving angular velocity vector.
In this animations the angular velocities about the local 1, 2, 3 axis are pre-set to vary sinusoidally. The magnitude and frequency are pre-set. However, the user has the ability to zero out the magnitude and observe combinations of rotations.
Note, however, that the rotations are cummulative.
