A uniform stainless steel guitar string of length and diameter d is stretched between two rigid supports by a
tensioning force F1, which is required to tune the string to the E note of a C scale. The string is then struck near
the quarter point with a force F2. Determine the fundamental frequency, f1. Also, show that only the odd-numbered
frequencies produce a response at the midpoint of the string for this excitation. Figure 76.1 Guitar String Problem Sketch Material Properties
