Two pieces of steel wire with identical cross sections
Chapter 14, Problem 14.38(choose chapter or problem)
Two pieces of steel wire with identical cross sections have lengths of L and 2L. The wires are each xed at both ends and stretched so that the tension in the longer wire is four times greater than in the shorter wire. If the fundamental frequency in the shorter wire is 60 Hz, what is the frequency of the second harmonic in the longer wire?
