Question $1$

For the beam shown below, $F=55N$ and $L=9.$

a$)$ Determine the reactions at the supports $A,B$ and $C$ assuming $E$ is constant. Consider bending

strain energy only.

b$)$ Determine the deformed shape, shear force, and bending moment diagrams of the beam.

$($Please keep $3$ decimal places in the intermediate stages of your calculation to accuracy of your final

answers.$)$Part a$)$ Task $3$:

$x_1$ is for member $AD($Make a cut between A and $D,$ and use LH freebody$).$

$x_2$ is for member DB $($Make a cut between $D$ and $B,$ and use LH freebody$).$

$x3$ is for member $BC($Make a cut between $B$ and $C,$ and use $RH$ freebody$).$
