Question

The diameter of a guitar string is .00127m, and its length is .6477m. the string is moving at a frequency of 82.4Hz. What is its mass?

Answer 1

The frequency will be a the sqrt (F/mu), where F is the tension and mu is the mass per unit length. We lack T. Tighter, lighter strings vibrate faster.

Answer 2

Thank you. But how would one find tension if mu is unknown?

Answer 3

The tension would have to be given to you. I don't know why it wasn't.

Answer 4

Thank you for your help!
