AI Thread Summary
Catgut strings on musical instruments are wrapped with fine wire to increase their mass and alter their frequency. This wrapping allows for higher tension without breaking the string, enhancing sound quality and projection. The choice of wire material also impacts the string's maximum tension and overall performance. The discussion highlights the interplay between tension, mass, and sound production in string instruments. Understanding these factors is essential for both musicians and those studying the physics of sound.

What is the reason that catgut strings on some musical instruments are wrapped with fine wire?
 
Physics news on Phys.org
The frequency of the string depends on the tension and the mass of the string.
You can change the mass by adding extra wire, you can also change the maximum tension by choosing a different material.
 
It looks like someone is doing a section on sound in their physics class.
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Effect of mass on the acceleration of an elastic pendulum?'

I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?

Thread 'Inclined treadmills and Galilean Invariance'

This has been discussed many times on PF, and will likely come up again, so the video might come handy.
