Moments and Couples
... the magnitude of the moment of a couple is equal to the forces multiplied by the distance between the forces. Reactions for a body in equilibrium are equal and opposite to the forces and moments generated at that point. ...

... The moment of the couple about O is: M = rA x (F) + rB x (-F) = (rA - rB) x F By triangle law of vector addition, rB + r = rA or r = rA - rB So: M = r x F This result shows that a couple moment is a free vector i.e can act at any point, since M depends only on the position vector directed between th ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
