A beam segment with its internal shear forces at sections A and $B$ is shown along with a sketch of the cross$-$sectional

dimensions. Consider the block on the left of the beam, shown as area $(1),$ and answer the following questions: $[$L $=16$

in$.,V_A=1140lb,V_B=1140lb,a=2$ in$.,b=3\mathrm{.}5in.,c=13$ in$.,I=585\mathrm{.}8in.{?}^4]$

Determine the first moment of area $(Q).$
