The one exerted by the sun and moon on the earth results in the twenty-six thousand year precession of the earth's axis of rotation, and this quantity is the time derivative of angular momentum.
When this quantity is absent, Poinsot's construction represents one phenomenon that usually requires it to be present, while the type of that phenomenon "induced" by this quantity is also called the "gyroscopic" kind. The one exerted by the sun and moon on the earth results in the twenty-six thousand year precession of the earth's axis of rotation, and this quantity is the time derivative of angular momentum. FTP, identify this quantity, equal to the cross product of lever arm and force applied, which refers to the effect that an action has in rotating a body around some axis.
When this quantity is absent, Poinsot's construction represents one phenomenon that usually requires it to be present, while the type of that phenomenon "induced" by this quantity is also called the "gyroscopic" kind.
