Question

A steel cable on a bridge has a linear mass density of 15 kg/m. If the cable has been pulled taunt with a tension of 5536 N, what is the speed of a wave on it?

Answer 1

`\begin{gathered} T=5,536N \\ \mu=15\text{ kg/m} \\ v=? \\ v=\sqrt{(T)/(\mu)} \\ v=\sqrt{\frac{5,536N}{15\text{ kg/m}}} \\ v=19.21\text{ m/s} \\ The\text{ speed of a wave on the cable is 19.21m/s} \end{gathered}`
