a$)$ Derive equations for the shear force $\backslash ($ V $\backslash )$ and the bending moment $\backslash ($ M $\backslash )$ for any location in the beam. $($Place the origin at point A$.)$

b$)$ Plot the SFD $\backslash$& BMD using the derived functions.

c$)$ Determine the location and the magnitude of the maximum bending moment.
