Question $1$

$12\mathrm{.}5$ Points

Use the graphical method to construct the shear$-$force and bending$-$moment diagrams for the beam shown. Let $a=2\mathrm{.}5m,b=4\mathrm{.}5m,w=55k\frac{N}{m}$ and $P=50kN.$ 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.

Determine the shear force acting at

$x=2\mathrm{.}5-m($i$.$e$.,$ just to the left of $B)$
