A steel wire of diameter 2.000 mm and length 1.000 m is attached between two immovable supports. When the temperature is 60.00 Celsius the tension in the wire is (essentially) zero. The temperature is then reduced to 20.00 Celsius. Young's Modulus for steel is 2.000E10 Pa and the density of steel is 7.860E3 kg/m3 and the coefficient of linear expansion of steel is 11.0E-6 C-1
a) Find the tension in the steel wire.
b) What would the velocity of a traveling wave be at this lower temperature?
c) Find the pattern of allowed frequencies of standing waves allowed on this wire.
