String is a solid but it does not show longitudinal waves
A string is a solid but it does not show longitudinal waves. Well it is known that a string cannot be compressed but only be given tension but a answer with a sound scientific reasoning will be accepted.

Longitudinal waves do propagate in string. That is how "tin can phones" work.

Why would you expect it not to have longitudinal waves?
If you have a steel bar and you hammer on one end, you get compression waves. They travel as fast as the inter-atomic forces transmit them from one atom to another.
If a string is under tension, and you hammer backward against whatever it's tied to, I'd expect the string to transmit tension waves. The amount of tension would increase and decrease, and the waves would travel as fast as the inter-atomic forces transmit them from one atom to another.
It makes perfect sense that when you pluck a string under tension, you make both transverse and longitudinal waves. Beginning physics students pay attention to the longitudinal waves because they are a metaphor for transverse light waves, and they can be visible.
So when you make a guitar or a violin, does the sound come from the transverse waves from the string causing the air inside the sound box to vibrate, which causes the front panel to vibrate, which vibrates the air outside the soundbox?
Or is is from the longitudinal waves from the string causing the neck and bridge of the instrument to vibrate, which causes the front panel to vibrate, which vibrates the air inside and outside the soundbox.
If it's the latter, you could make a stringed instrument that had the soundbox at one end with the strings attached to it normal to the surface, and it would make sound even though the strings' transverse motion doesn't have much opportunity to affect the soundbox or the air inside it.
And you can.
So is it more likely that this instrument has its sounding board vibrated by the longitudinal tension of the strings, or the air moved by their transverse motion?
