Oops, I stand corrected -- thanks, Frank. Once again I read too hastily. A
*mass*/spring combination mimics an inductor/capacitor, of course. A
damper adds resistance. So a spring/damper combination would act more like
an RC or RL circuit, but with a little stray L or C from the spring's
mass.

Hope I don't have to give up my new title. Titles really impress folks in
some parts of the world.

No problem Roy. To be exact a mass is equivalent to a capacitor.
As in Newton's 2nd law: f = m*dv/dt, and its electrical analog
i = c*dv/dt, where "v" refers to velocity in the mechanical case,
and voltage in the electrical. I think this qualifies me to place the
letters "ASI" after my name. Well; I must admit I took a quick
look at my physical systems text book, so hope it does not
disqualify me.
