Q3. An insulated heated rod with a uniform heat source can be modelled with Poisson equation dT dx = -f(x) (a) Given a heat source f(x) = 25 C/m and the boundary condition T(x=0) = 40C and T(x=10) = 200C, solve for the temperature distribution in the system using the Finite Difference Method with Ax = 2. (b) (b) Repeat this problem but for the spatially varying heat source: f(x) = 0.12x* - 2.4x + 12x T (c) If (dx without attempting to resolve it..
