\\; Two horizontal wires are joined end to end, each with a diameter of 2.000 mm. The two joined wires are connected to xed points a total distance of 4.00000 m apart. When both wires are at a temperature of 400C, each wire has an unstretched length of 2.00000 m, and the tension in each is negligible. The first wire is made of steel and extends from X = 2.00000 m to x = 0, and the second is made of brass and extends from X = 0 tox = 2.00000 m. The temperature of both wires is then lowered to L5.0C, and the wires stayr joined together as the',f cool. The steel wire is comaosed of an alloy.r that has an average coefcient of linear expansion of '_.10 x '_0'5{'7(3]_1 and a Young's modulus of 2.00 x 101'" N/mz. The brass wire is composed of an alloy that has an average coefficient oflinear expansion of 1.00 \\ :10'5[C}I'l and a Young's modulus of 9.1.0 x 101: Ny'mz. {Due to the nature of this problem, do not use rounded intermediate values in your calculationsincluding answers submitted in WebAssign.) (a) At the final, lower temperature, what is the X-coordinate {in m] of the junction between the wires? m {b} At the final, lower temperature, what is the tension {in N] in the wire? N
