5. If the lengths of two bars of different solids are inversely proportional to their respective coefficients of linear expansion at the same initial temperature, the difference in length between them will be constant at all temperatures. That means one way to construct a device with two points whose separation remains the same in spite of temperature changes is to bolt together one end of two bars having different coefficients of linear expansion as shown below. What should be the lengths of a steel (a = 11 x 10 / C") and a brass (a = 19 x 10 / C") bar at 0'C so that at all temperatures their difference in length is 0.30 m? 26. A composite rod is made by joining two rods of different materials but with the same cross-sectional area as shown below. Design such a composite rod using steel (a = 11 x 10/ C') and brass (a = 19 x 10% / C") whose total length is 52.4 cm and whose effective coefficients of linear expansion is 13 x 10/ Co. Compute the lengths of the steel and brass rods that must be used. Neglect changes in cross-sectional area of the rods. 1 2
