Mechanical impedance

Mechanical impedance is a measure of how much a structure resists motion when subjected to a harmonic force.

It relates forces with velocities acting on a mechanical system.

of the applied force and can vary greatly over frequency.

At resonance frequencies, the mechanical impedance will be lower, meaning less force is needed to cause a structure to move at a given velocity.

Mechanical impedance is the ratio of a potential (e.g., force) to a flow (e.g., velocity) where the arguments of the real (or imaginary) parts of both increase linearly with time.

Examples of potentials are: force, sound pressure, voltage, temperature.
