Consider the square cross section of a long solid bar as shown in the diagram below. T(x,L) Tsin(27x/L) T(0,y)=To YA L X = T(L,y)=Tsin(3y/L) T(x,0)=To For the coordinate system shown in the figure, the temperature distributions on the boundaries are T(x,0) = To, T(0,y) To, T(x,L) = Tsin(2+x/L), and T(L,y) Tsin(37y/L), where To and T are constants. Find an expression for the temperature distribution T(x,y) in this solid. =
