My EE students, noting that the characteristic equations are the same,
regularly convert mechanical problems (of the mass-spring-damper type) into
electrical problems, solve, and then convert back to mechanical answers.
Some ME students catch on and some just do not get it. Of course, it helps
if one is using SI units all round. I continue to be in awe of MEs who
always seem to know whether the "pounds" they are talking of are
sort-of-like mass, or sort-of-like force, or money. I have even had it
suggested that energy and power are sort-of the same thing.


I am keen on Roy being the collector of titles. I have quite enough for
a lifetime. 73 Mac N8TT etc.

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.
