Your friend, an artist, has been thinking about an interestingway to display a new wind sculpture she has just created. In orderto create an aural as well as visual effect, she would like to usethe wires needed to hang the sculpture as a sort of a stringinstrument.
She decides that with two wires and some luck, the wires will sounda C-major dyad (C - 262Hz, G - 392 Hz) when the wind blows (note: Adyad is part of a chord.). Her basic design involves attaching apiece of wire from a hook on the ceiling, attaching a second pieceof wire to the first wire, and then hanging the 50 pound sculpturefrom the second wire. Your friend tells you that she has beensuccessful in hanging the sculpture but not in "tuning" the sound.Desperate for success, she knows you are taking physics and asksfor your help. Before you tackle the analysis, you use yourknowledge of waves to gather some more information. You takesamples of the wires back to your lab and measure their linear massdensities and find them to be 5.0 g/m and 8.3 g/m. What is youradvice? Assume that the junction of the two wires can'tvibrate.
