+ Both ends of a 4m long metal rod are kept at a temperature of 240°C at x = 0 and 120°C ot x = 4m. The diameter of the bar is 0.2m, the conductivity Coefficient is 400 W/m°c, the ambient temperature is 20°C and the heat transfer to the environment is by convection. Coefficient is 10 w/m 2. 로 Find the temperatures of T₁, T2, and T3 at these three nodes using the finite difference method by selecting 3 nodes inside the bor.
