Stationary Waves

Stationary Waves problem 7

Fixed at both ends, a 0.5 m long steel wire oscillates at a frequency of 400 Hz.

  • With what tensile stress is the wire tensioned?

  • If the wire is then cooled by 15 K, by how much does the natural oscillation frequency change?

The density of steel is , the young modulus of steel is , the linear expansivity of steel is .
