Indirect analogy
Conventionally, the "indirect" analogy consists in associating the mechanical speed of a mass, with the electrical voltage.
From an energetic point of view, this consists in representing the kinetic energy of a mechanical system as a potential energy stocked in a capacitor.
The same reasoning shows that the potential energy stocked in the deformation of a mechanical element is represented by the energy stocked in an inductor under the influence of the current flowing through it.
The "indirect" analogy therefore associates an electrical admittance with a mechanical impedance: it is sometimes called "mobility analogy".
The representation of the damping and lever are the same for both analogies. The difference is that the roles of force and speed are reversed.
