Answer 3

Answer 4

Yes, you can do it, the device can be called " The acoustic motor".

It is a resonant mechannical system, the resonance can amplify the input energy to the level you want, is the internal energy of the system transfered to the output load, mass and elastic propieties of the system of the motor are the resonant parameters for consideration
