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 m
2
. The left end has a
constant temperature of 100 C, and the right end has a constant temperature of
300 C.
