What keeps these inflation monitors from reporting a false low tire when you are taking a long radius turn on a highway?
When a string breaks on a guitar, the sudden release of that string’s tension makes the rest of the strings go sharp, so the wood does flex.
Also, when restringing a guitar, by the time you have the last sting up to pitch, you have to go back to the first string and tune it again because it’s now really flat even though you had it to pitch when you put it on, you often have to go through this several times before they are all in tune.
The wood compresses more than the steel stretches.
