In the two$-$dimensional body illustrated, the gradient at surface $A$ is found to be del$\frac{T}{d}$ely$=30\frac{K}{m},$ where $w_A=1\mathrm{.}0m$ and $w_B=$

$1\mathrm{.}8$ m $.$ What are del$\frac{T}{d}$ely and del$\frac{T}{d}$elx at surface $B?$

$(del\frac{T}{d}$ely${)}_B=$

K$/$m

$(del\frac{T}{d}$elx${)}_B=$

K$/$m
