A flexible string with mass per unit length ρA is fixed at the ends and stretched to an initial strain εo. Determine
the stress σ and force F in the string under these conditions. Determine the first three natural frequencies fi of
lateral vibration of the stretched string. Figure 53.1 String Under Tension Problem Sketch Material Properties
