$3.)$ Determine the maximum shear force $($absolute value$)$ and positive and negative max bending moments in the beam. Also specify the locations on the beam where they occur. Let $a=2\mathrm{.}7ft,b=8\mathrm{.}1ft,c=0\mathrm{.}2ft,M_A=6600lb*ft,P=2000lb,$ and $w=540l\frac{b}{f}t.$

$[$Answer: Vmax $=2370$ in section ED$,$ Mmax $(+)=2504lbft$ at $x=9\mathrm{.}10ft,$Mmax$(-)=-6600lbft$ in section $AB]$
