WebMechanical impedance and mobility The mechanical impedance and not be given here. The units after of motion relative to the direction of mobility (for simple harmonic mo- each ratio are Sl-units*. force when this is not obvious from tion) are defined as the complex ra- the measurement conditions or WebMechanical 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. The mechanical impedance of a point on a structure is the ratio of the force applied at a point to the resulting velocity at that point.
WebThe theorem can be extended to alternating current circuits that include reactance, and states that maximum power transfer occurs when the load impedance is equal to the complex conjugate of the source impedance. The mathematics of the theorem also applies to other physical interactions, such as: mechanical collisions between two objects, WebMechanical impedance is the ratio of a potential to a flow where the arguments of the real parts of both increase linearly with time. Examples of potentials are: force, sound pressure, voltage, temperature. Examples of flows are: velocity, volume velocity, current, heat flow. Impedance is the reciprocal of mobility.
