Problem $3-24($Use Row $b$ from Table $P3-1,I=0\mathrm{.}7,a=0\mathrm{.}2,w=80,F=850)$: Solve for reactions using the singularity functions only then modify the matlab code file $($singularity functions,m darr $)$ to plot the shear force and bending moment diagrams to find $V_{\text{m}\text{a}\text{x}}$ and $M_{\text{m}\text{a}\text{x}}($report the values with the highest magnitude, e$.$g$.$ if the moment ranges from $-20$ to $10,$ you would report $-20$ as your answer$).$
