Analyse the beam in Figure $1$ using the Force Method with the primary structure created by inserting hinges at $A,$

$B$ and $C($hence the bending moments at $A,B$ and $C$ are the 'redundant forces'$).$ Draw the free body diagram, the

shear force diagram, and the bending moment diagram. Assume that the flexural rigidity $EI$ is constant.

Write answers in the space provided below and submit this page, along with a cover page and all

workings attached.

Note: Please use the graphical integration technique instead of using using functions integration. AgF$($xg$)$ where A is the area of G function. F$($xg$)$ is the value of Ag centroid on F function. Also calculate the flexibility coefficients.
