pitch and thickness

[Don]

Hi Martin,

This is of interest to all I think:

"The cross-sectional area of the spoke and the mass per unit length m are
exactly proportional to each other. Therefore, for two different strings or
wires of equal length, one thick and another thin, the frequency is the
same if the tension per unit of cross-sectional area is the same. One way
to think of this is to imagine two identical spokes side by side, both of
the same gauge and at the same tension. They vibrate at the same frequency.
Now imagine lightly connecting them together all along their length. They
still vibrate at the same frequency. Finally, imagine merging them into
one, thicker spoke. It still vibrates at the same frequency."
