							Dear student Tension in the string is developed in the wire the compression due to cooling is balanced by the expansion due tension generated Thus FL/AY = Lalpha * delT F = YAalpha *delT frequency of viberation = f = 1/2L (sqrt (F/mew)f is directly proportional to (sqrt (YAalpha * delT ) )row *A*L = mew*Lf is directly proportional to sqrt (Y *alpha / row)
