A steel of length 1m, mass 0.1 kg and uniform cross – sectional area 10-6 m2 is rigidly fixed at both ends. The temperature of the wire is lowered by 20° C. If transverse waves are set up by plucking the string in the middle, calculate the frequency of the fundamental mode of vibration. Given for steel Y = 2 x 1011 N/m2Α = 1.21 x 10-5 per °C
