Hey I keep getting this wrong! pleqse explain step by step. The cantilever shown in the figure consists of two structural$-$steel channels size $3in.,5\mathrm{.}0lb\frac{f}{f}t.$ Using superposition, find the deflection

at $A.$ Include the weight of the channels. Take the magnitude of force $(F)$ to be $145$ lbf $.$ Take $L$ as $52$ in and $w$ as $4\mathrm{.}400lb\frac{f}{i}n.($Round the

final answer to three decimal places.$)$

The deflection at point $A$ is

$0\mathrm{.}070$ inch in the

downward

direction
