For the beam below:

$($a$)$ Develop the function for shear, V$($x$),$ and bending moment, M$($x$),$ using the Method of Sections approach. Reference x from the far$-$left point of the beam.

$($b$)$ Plot the shear and moment diagram for this beam using the equation you developed in $($a$).$ Include the values of the shear and moment at x $=0,$ x $=5$ ft and x $=10$ ft
