- A Piece Of Musie Wire With A Mass Of 0 745 G Is Used In A Piano For The Key Of B Below High C The Wire Is To Be Tuned T 1 (17.36 KiB) Viewed 41 times
A piece of musie wire with a mass of 0.745 g is used in a piano for the key of B below high C. The wire is to be tuned to a fundamental frequency of 988 Her Knowing that the wire is anchored between tightening posts that are 41 cm apart, determine the tension in the wire required to produce the correct note. Find the temperature change needed in the room for the note frequency to drop by 2% if the music wire has a coefficient of themal expansion of 12×10−71CC, a diameter of 1/16−′, and a modulus of elasticity of 30×106 psi or 207GPa
