I.C 02/A/ Use the Crank-Nicolson method to solve for the temperature distribution of a long thin rod with a length of 10 cm and the following values: k = 0.49 cal/(s cm °C), Ax = 2 cm, and At = st 0.1 s. Initially the temperature of the rod is 0°C and the boundary conditions are fixed for all times at 7(0, t) = 100°C and 7(10, t) = 50°C. Note that the rod is aluminum with C = 0.2174 cal/g °C) and p = 2.7 g/cm³. List the tridiagonal system of equations and determined the temperature up to 0.1 s.
03 A thin rod of 3 cm length having a thermal diffusivity coefficient (a) of 0.835 cm²/s is initially kept at a temperature of 0 °C. The rod is insulated at all points except at its ends which are kept at all times at T(0) -5 °C and T(3) = 10 °C. Use the explicit method to solve for the temperature distribution in the rod at t= 0.2 second using the following information; Ax=1 cm, At = 0.1 second, and λ = a At/Ax².
