1. The problem statement, all variables and given/known data A extremely strong wire of exotic material has a radius of 0.1 mm and a length of 5 m. A 1000 kg mass is hung vertically from the wire. The speed of sound in the wire is observed to be the same as the speed of a transverse wave on the wire. What is the Bulk Modulus of the material? (in N/m2 ) 2. Relevant equations Speed of Sound in solid: v=√(B/ρ) B=-ΔP/(ΔV/V) 3. The attempt at a solution I honestly don't know where to start. All the examples in my text give a change in volume or pressure, which would be simply using Equation 2. I'm assuming you find the density of the wire somehow, but I don't have the mass of the wire. Any guidance would help!
