Question $4(25$ marks$)$

For the beam shown in Figure Q$4,$ the externally applied loads can be defined as: $\backslash ($ P$=18\backslash$mathrm$\{$kN$\}$ ; w$=5\backslash$mathrm$\{$kN$\}/\backslash$mathrm$\{$m$\}$ ; M$=8\backslash$mathrm$\{$kNm$\}\backslash ).$

Hence for this beam:

i$.$ Determine the support reactions at $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash ).$

ii$.$ Using the Method of Sections, derive equations defining the internal shear forces and bending moments along the entire length of the beam.

iii. Draw and annotate the shear force and bending moment diagrams.
