A rod of 20 cm in length produces heat of q ‘’’ = 0.05 W / m3. The bar is cooled symmetrically from both sides. It is required that the temperature at the symmetry axis of the rod to be To= 30oC. The thermal conductivity coefficient (k) of the rod varies depending on the temperature. k = 20 (1 + T2)

Find the temperature distribution in the bar, in constant conditions.
