For the one-dimensional composite bar shown in Figure P13–1, determine the interface temperatures. For element 1, let K_xx = 200 W/(m . °C); for element 2, let K_xx = 100 W/(m . °C); and for element 3, let K_xx = 50 W/(m . °C). Let A = 0.1 m². The left end has a constant temperature of 100 °C, and the right end has a constant temperature of 300 °C.
