2. Consider a heat conduction problem described in the figure. Inside the bar, heat is generalfrom a uniform heat source Qg = 10W/m3, and the thermal conductivity of the material k = 0.1 W/m/0C. The cross-sectional area A = 1 m2. When the temperatures at both ends a fixed to 0oC, calculate the temperature distribution using:

(a) two equal-length elements and (

three equal-length elements. Plot the temperature distribution along the bar and compare wj the exact solution.

r=ooc Qg= 10 W/m3 r=o0c
