Figure 18-59 shows a composite bar of length L L1 L2 and consisting of two materials. One material has length L1 and coefficient of linear expansion a1; the other has length L2 and coefficient of linear expansion a2. (a) What is the coefficient of linear expansion a for the composite bar? For a particular composite bar, L is 52.4 cm, material 1 is steel, and material 2 is brass. If a 1.3 105 /C, what are the lengths (b) L1 and (c) L2? L1 L2Figure 18-59 96.
