Determine the equilibrium temperature distribution for a one-dimensional rod composed of two different materials in perfect thermal contact at x = 1. For 0 < x < 1, there is one material (cρ = 1,K0 = 1) with a constant source (Q = 1), whereas for the other 1 < x < 2, there are no sources (Q = 0, cρ = 2,K0 = 2) (see Exercise 1.3.2) with u(0) = 0 and u(2) = 0.

Reference Exercise 1.3.2:

Consider the equilibrium temperature distribution for a uniform one-dimensional rod with sources Q/K0 = x of thermal energy, subject to the boundary conditions u(0) = 0 and u(L) = 0.

*(a) Determine the heat energy generated per unit time inside the entire rod.

(b) Determine the heat energy flowing out of the rod per unit time at x = 0 and at x = L.

(c) What relationships should exist between the answers in parts (a) and (b)?
