BISOPE series 32- How is forced frequency different from natural frequency?

----------------------------------------------------------------------------------------------------------------------------------------

When playing an acoustic guitar, when a guitar string is plucked according to a musical notation chord, each of the six strings (strings) generates a harmonic sound that shows a special timbre according to the chord, even if it produces a different sound. The guitar sound is unique for each string, and the pitch of the sound is different from each other. To understand this reason, if you take a good look at it with a little common sense, you can understand that the sound is 'uniquely different' depending on the length of the guitar string being plucked, the type of guitar string, and the degree to which the guitar string is tightened.

On the other hand, the vibration generated when the fan is operated, and the RPM (revolutions per minute) that fluctuates whenever the accelerator is pressed are different from the unique characteristics of the above guitar strings. In other words, this is a newly created thing, a 'forced creation', on the other hand, it is different from what the guitar string originally had, in other words, it does not generate sound at all unless it is plucked by hand.

 

​Forced frequency

 

When a force is applied, both a natural frequency and a forced frequency occur, but .....
