tonequester here. Greetings to ALL. I have posted about acoustic resonance on my last couple of posts, and have been given much good info. I have one more post concerning concerning this topic.. I am going to do an experiment to find out the answer to my query, IF there is no definitive scientific/physics related answer forthcoming. However, IF there is, it would save me the time and expense of the experiment. My query is this : If one were to mount 2 guitar strings of the same gauge, one rigidly mounted to a steel bar, and the other so mounted to a wooden bar, of the same dimensions, which one, if equally "plucked", would vibrate for the longest period of time ? I would of course mount both strings above each bar the same distance, perhaps 1/4 inch, and would have to devise a method for equally plucking or striking the string, as well as placing both strings under equal tension. Also, would it matter if the string were single stranded, or wound, as guitar strings are of both types(don't think it would matter). I believe that an answer to this question will satisfy, what I have been trying to determine all along, but was not insightful enough to realize before, exactly how to post. I also pledge that my next post will not concern acoustics ! Any and all comments are always welcome, but surely there is a simple answer, based on the Laws of Physics, that will encompass my curiosity. Thanks in advance....tonequester.
