An uncoated, solid cable of length L = 1m and diameter D = 40 mm is exposed to convection conditions characterized by h = 55 W/m2 ·K and T[infinity] = 20°C. Determine the maximum electric current that ca be carried by the cable if it is pure copper, pure aluminum, or pure tin. Calculate the minimum wire temperatures. The electrical resistivity is Re = 10 x 10-8 Ω·m for copper and aluminum at their melting points, while the electrical resistivity of tin is Re = 20 x 10-8 Ω·m at its melting point
