A cantilever beam ABCD is subjected to a linearly distributed load, with qo $=2$ kN$/$m$,$ two concentrated loads, F$1=10$ kN at B and F$2=15$ kN at D$,$ and a point moment at B as shown in Figure $1\mathrm{.}1.$ The angles of the point loads are: $1=30$o and $2=60$o and the dimension a $=6$ m$.$Calculate the internal loadings at the midpoint of section BC using the method of sections.
