Analogy: Gear Backlash and Hysteresis

Gear backlash is a discretized version of hysteresis in materials.

This can be seen by comparing the hysteresis plot (displacement field vs. electric field) to the backlash plot (output vs. input).

It makes sense because depending on the direction of the input (field applied to a material), the output of the system exhibits a different set of responses.
