Условие
When a force is applied to a small region of the piezo crystal, due to electro-mechanical coupling, the crystal will try to curve. However, the wooden plates will prevent this, and as a result, mechanical stress will appear in other parts of the crystal, too.
How much will the electrical response change when the force is applied to a small area of the crystal? Consider only the linear range of the response.
