The other cool analogy that falls out of this is the synchronization
of positioning or phase angle (for AC power systems). If you have a
long shaft with a gear on each end, and you index one tooth on each
gear, the rotational position reletive to each other depends on the
ammount of twist in the shaft...which depends on the touque being
delivered.
In AC power systems, the phase angle of the AC wavefoem between a
generator and the load point depends on the inductance of the
powerline and the amount of current being pushed.
