The fist (thin) string in a guitar should be two octaves higher than the sixth (thick) string, that is, its fundamental frequency is four times higher. If both strings are equal in length and under the same tension, what would the ratio of their linear mass densities be?

Solutions

Expert Solution

the fundamental frequency of the first string is 4 times higher than that of the sixth string,

so we can say that f1 = 4f6

now, we know that f = 1/2L (T/)

where L is the length of the string, T is the tension and is the linear mass density

so,

f1 =1/2L (T/1)

f6 = 1/2L (T/6)

therefore

f1/f6 = (6/1)

4 = (6/1)

1/6 = 1/16

A thin string of length L = 3m is pinned at the two ends. Based on the material linear density ρ and on the traction force T, it can be assumed that √ T/ρ = 2 m/s. The string is initially straight when, at time t = 0, it is tapped in two narrow intervals (1 − 1/8, 1 + 1/8) and (2 − 1/8, 2 + 1/8) with opposite velocities +1m/s and −1m/s, respectively. i) Derive the field equation...
