Use the graphical method to construct the shear$-$force and bending$-$moment diagrams for the beam shown. Let $a=4\mathrm{.}0m,b=2\mathrm{.}5m,c=3\mathrm{.}0m,d=4\mathrm{.}5m,w_{AD}=65k\frac{N}{m},w_{DE}=45k\frac{N}{m},P_B=95kN,$ and $M_A=60kN-m.$ Construct the shear$-$force and bendingmoment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise.
