Randall D. Knight — Superposition: Problem Problem_38

Tendons are, essentially, elastic cords stretched between two fixed ends. As such, they can support standing waves. A woman has a 20-cm-long Achilles tendon—connecting the heel to a muscle in the calf—with a cross-section area of \(90\text{ mm}^2\). The density of tendon tissue is \(1100\text{ kg/m}^3\). For a reasonable tension of \(500\text{ N}\), what will be the fundamental frequency of her Achilles tendon?
