CP A 5.00-m, 0.732-kg wire is used to sup-port two uniform 235-N posts of equal length (?Fig. P15.55?). Assume that the wire is essentially horizontal and that the speed of sound is 344 m/s. A strong wind is blowing, causing the wire to vibrate in its 5th overtone. What are the frequency and wavelength of the sound this wire produces?
Solution 62P Step 1 of 5: For the 5 th overtone, n = 6. The wire has = m = 0.732 kg= 0.146 kg/m L 5 m Forces at the pivot produce no torque because the rotation axis to be at the pivot.
