How Efficient is Piezoelectric Quartz When Struck with a Hammer?

AI Thread Summary
Piezoelectric quartz converts mechanical energy into electrical energy, but its efficiency is less than 100%. When struck with a hammer delivering 100 joules of kinetic energy, the output will be lower due to energy loss from molecular vibrations and internal resistance. Exact energy conversion rates depend on experimental conditions and the specific properties of the quartz. Some participants suggest that the impact may result in broken quartz rather than usable electrical energy. Overall, the efficiency of piezoelectric quartz in this scenario is limited.

Lets say I have a hammer, and a piece of piezoelectric quartz. If I hit the quartz with the hammer with the kinetic energy of 100 joules, how many joules can I get out of the quartz?

After researching a lot on word "piezoelectric" , I think that your question can just be answered by the usual concept of "efficiency". So in this case when we hit "piezoelectric quartz" with hammer with the kinetic energy of 100 joules, we will probably get less than 100 joules of "electrical" energy out of the quartz. This is because no object is 100% efficient. Some of the kinetic energy is used up in vibrating the molecules and internal resistance , etc... I CANNOT say exactly how much less can be obtained (that depends on experimentation now ).

I think the result of your experiment will not give you any "joules". In my estimation, you will have only a pile of broken quartz crystals.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
