4 Two long bars, 1 and 2, are initially at uniform temperatures To and T02, respectively. The two bars are brought into perfect contact at their ends and allowed to exchange heat by conduction. Assuming that the bars are insulated along their surfaces, determine: [a] The transient temperature of the bars. [b] The interface temperature.
