Part $1$

Use the graphical method to construct the

shear$-$force and bending$-$moment

diagrams for the beam shown. Let $a=1\mathrm{.}5$

$m,b=2\mathrm{.}5m,w_{AB}=135k\frac{N}{m},w_{BC}$

$=75k\frac{N}{m},P_B=60kN,$ and $P_C=120kN.$

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.

Calculate the reaction forces $A_y$ and $M_A$

acting on the beam. Positive values for the

reactions are indicated by the directions

of the red arrows shown on the free$-$body

diagram below. $($Note: Since $A_x=0,$ it has

been omitted from the free$-$body

diagram.$)$

Answers: $A_y=$

$kN,M_A=$

$kN-m.$
