1) Reaction Calculation:
$$ \begin{array}{c}{\sum \mathrm{Fy}=0} \\ {+\mathrm{R}_{\mathrm{A}}-(15 \times 2.5)=0} \\ {\mathrm{R}_{\mathrm{A}}-37.5=0} \\ {\mathrm{R}_{\mathrm{A}}=37.5 \mathrm{kN}}\end{array} $$
2) SF Calculation:
$$ \begin{aligned} \text { SF at } A &=+37.5 \mathrm{kN} \\ \mathrm{C} &=+37.5-(15 \times 2.5)=0 \mathrm{kN} \\ \mathrm{B} &=0 \mathrm{kN} \end{aligned} $$
3) BM Calculation
$\begin{aligned} \mathrm{BM} \text { at } …
