You have a pure copper electrical wire with a diameter of 0.205cm and an electrical resistance of 0.0053Ω/m. The wire is exposed to uniform convection of T_inf = 22.0°C, h_inf = 15.0 W/(m2-K). At steady-state conditions the wire carries 21.0 amps of current through it. Determine both the surface temperature and the maximum temperature of the wire.

Two metal bars are made of invar and a third bar is made of aluminum. At 0C, each of the three bars is drilled with two holes 40.0 cm apart.
