Natural FrequencyWhat does the natural frequency of an object depend on?

AI Thread Summary
The natural frequency of an object is influenced by its intrinsic properties, including material composition, shape, defects, temperature, and humidity. Calculating the natural frequency of real-life objects is often complex, making experimental determination the preferred method. In a discussion about sound production, it was clarified that plucking a guitar string in space would cause the string to vibrate, but sound waves would not propagate without a medium like air. The vibrations are confined to the guitar itself, as sound requires a medium to travel. Understanding these principles is essential for studying the behavior of objects and sound in different environments.

What does the natural frequency of an object depend on?

Whenever I try to look this up, I usually read that the natural frequency depends on "intrinsic" properties or a "variety" of factors. Is the natural frequency independent for each object/is there any universal factor the natural frequency depends on?

No, it's always going to be a complicated function of what the object's made of, its shape, whether it has defects, the temperature, the humidity, etc. Generally it's not feasible to calculate the natural frequency of a real life object it's pretty much always much much easier to just find it experimentally.
 
Okay thanks for that.

Somewhat unrelated, if you were to, let's say, take a guitar into space. The guitar strings each have their own natural frequency. However if you were to pluck one of the strings, would a frequency (and corresponding wave) be produced? Doesn't sound, which is produced from such an event, require a medium?

--- Nevermind

The object would just vibrate, no wave produced.

Yes. The medium is: first the string, then the guitar body. The wave would not, however, propogate beyond the physical confines of the guitar itself without the presence of a medium such as air (or any other mass in contact with the guitar).
 
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...
