One segment is made of aluminium and the other is steel. The effective coefficient of linear expansion of the two segment wire is 19 x 10^(-6)/C. The fraction length of aluminium is (linear coefficient of thermal expansion of aluminium and steel are 23 x 10^(-6).C and 12 x 10^(-6)/C, respectively )
