One of these is given by the gyromagnetic ratio times the angular momentum vector crossed with the
 magnetic field; that form of this phenomenon can cause the precession of the magnetic moment at the
 Larmor frequency.
One of these is given by the gyromagnetic ratio times the angular momentum vector crossed with the

 Larmor frequency. A set of "planetary" gears, beginning with a "sun" gear, comprise a device that acts as a
 "multiplier" of this quantity. When two applied force vectors oppose one another, they form a couple and
 their moment is known as this term. Power is the dot product of angular velocity at this quantity A second
 condition of static equilibrium is that in addition to force, the sum of these terms must be zero. This term is
 computed by taking the cross product of lever arm and force. For 10 points, identify this rotational analog
 of force.
