The steel used for piano wire has a breaking (tensile) strength pT of about 3×109N/m2 and a density ρ of 7800kg/m3. a.) What is the speed v of a wave traveling down such a wire if the wire is stretched to its breaking point? (m/s) b.) Imagine that the wire described in the problem introduction is used for the highest C on a piano (C8≈4000Hz). If the wire is in tune when stretched to its breaking point, what must the vibrating length of the wire be? (cm)
