Axial parallelism of Saturn's rings, in a 17th century work by James Ferguson (Scottish astronomer) Axial parallelism can be seen in the Moon's tilted orbital plane.This results in the revolution of the lunar nodes relative to the Earth, causing an eclipse season approximately every six months, in which a solar eclipse can occur at the new moon phase and a lunar eclipse can occur at the full ...
In other words, a couple, unlike any more general moments, is a "free vector". (This fact is called Varignon 's Second Moment Theorem .) [ 2 ] The proof of this claim is as follows: Suppose there are a set of force vectors F 1 , F 2 , etc. that form a couple, with position vectors (about some origin P ), r 1 , r 2 , etc., respectively.

Essentially, a gyroscope is a top combined with a pair of gimbals. Tops were invented in many different civilizations, including classical Greece, Rome, and China.

Torque-induced precession (gyroscopic precession) is the phenomenon in which the axis of a spinning object (e.g., a gyroscope) describes a cone in space when an external torque is applied to it. The phenomenon is commonly seen in a spinning toy top , but all rotating objects can undergo precession.
