The figure shows a composite bar of length L= L ₁ +L ₂ and consisting of two materials. One material has length L ₁ and coefficient of linear expansion ? ₁ ; the other has length L ₂ and coefficient of linear expansion ? ₂ .

(a) What is the coefficient of linear expansion ? for the composite bar? Put your answer in terms of L ₁ , L ₂ , of and ? ₂ . For a particular composite bar, L is 52.1 cm, material 1 is steel, and material 2 is brass. If a = 1.5x10 ^-5 /C?, what are the lengths

(b) L ₁ and

(c) L ₂ ?
