76. All surfaces of an infinitely long heating element, having a cross section in the shape of a cross, are maintained at 300 C. Due to symmetry, only a quarter of the cross section is shown in the figure. Heat is uniformly produced in the ele- ment at a rate of 100 kW/m³. Find the temperature distribution in the element at the locations shown in the figure. The element thermal conductivity is 35 W/m-K. All surfaces are exposed to a convection boundary condition of T₁ = 40 C and h = 1200 W/m³ C.
