Determine the temperature distribution (nodal temperatures) of the bar shown in the figure using two equallength finite elements with crosssectional area of 1m². The thermal conductivity is \(15 \mathrm{~W} / \mathrm{m} \cdot{ }^{\circ} \mathrm{C}\). The left side is maintained at \(300^{\circ} \mathrm{C}\). The right side is subjected to heat loss by convection with \(h=1.5 \mathrm{~W} / \mathrm{m}^{2} \cdot{ }^{\circ} \mathrm{C}\) and \(T_{f}=30^{\circ} \mathrm{C}\). All other sides are insulated.
