Use the graphical method to construct the shear$-$force and bending$-$moment diagrams

for the beam shown. Let $a=1\mathrm{.}5m,b=2\mathrm{.}5m,w_{AB}=105k\frac{N}{m},w_{BC}=60k\frac{N}{m},P_B$

$=45kN,$ and $P_C=95kN.$ Construct the shear$-$force and bending$-$moment diagrams on

paper and use the results to answer the questions in the subsequent parts of this GO

exercise.
