There's 1:1 correspondence between mechanical and electrical quantities
Basic:
- voltage U in volts V ~ force F in newton N ~ moment M in Nm
- current I in ampere A ~ speed v in m/s ~ angular speed omega in rad/s
- power P=U*I ~ P=F*v ~ P=M*omega
- resistance R=U/I ~ R'=F/v ~ R=M/omega -- (conductivity just the inverse)
Electrostatic:
- charge Q in As ~ position x in m ~ angle alpha in rad
- capacity C in As/V ~ linear-stiffness k in N/m ~ angular-stiffness in kappa in Nm/rad
- electric field E in V/m ~ ...
- dielectric constant epsilon in (As)/(Vm) ~ ... ?
- D ...
Magnetostatic:
- ? ... ~ mass m in kg ~ moment of intertia kg*m^2
- ? ... ~ linear impulse kg*m/s ~ ...
Note that there are also 1:1 corresponcences to the inverse quanities (switching current with volatge - everything else follows automatically).
One can build mechanical circuitry (out of mechanical circuit elements) just as one does with electrical elements.
