Question

Problem 23

Answer 1

Given information

Given:

A string instrument is a piano. When you wrap the wire around a string, it thickens it.

 

They will vibrate more slowly as a result of this. As a result, the frequency will be reduced. The frequency of the string's vibration is determined by its tension, length, and thickness.

Why do the strings used for the lowest-frequency notes on a piano normally have wire wrapped around them?

Step-by-step explanation

Step 1.

When two steel strings of identical length and tension are compared, the string with the larger mass has a lower resonance frequency.

We may increase the mass of the string by wrapping it in the wire without affecting the length or tension of the string, resulting in a string with a low fundamental frequency.

This may be explained theoretically by combining the basic frequency of oscillation for a string with both ends fixed and the formula for the speed of waves on the string to obtain the new frequency.
