For resonance to occur you need a
capacitor/inductor, or mass/spring. All components of either mechanical
or
electrical circuits require the solution of the same simple differential
equation, such as i = C*dv/dt etc.

No-one was arguing that that was not the case. A spring might have the
mechanical equivalent of reactance, but a damper will most certainly
not - hence the rubbish posted by the OP, where he believes that
dampers store energy. They do not, and therefore cannot have the
mechanical equivalence of a reactance. Therefore, resonance is not
possible with such a system. In the extreme, the OP was reduced to
likening dampers to bicycle pumps, a sure sign of a failure to grasp a
fundamental point (and hence the error of his assertion).

I am not aware of a damper ever being considered a storage device.
Capacitance is equivalent to mass, Inductance is equivalent to a spring, and
resistance equivalent to a damper. Am I missing something?

Anyway will read later posts and see what I can get out of it.
