A beam is supported by a roller at point $\backslash ($ A $\backslash )$ and a pin at point $\backslash ($ C $\backslash ).$ A downwards force of $6$ kN acts on the left end of the beam, and a distributed load pushes down on the beam in the position shown. Another downwards force of $\backslash ($ F$\_\{1\}=2\mathrm{.}1\backslash )$ kN acts a point B $.$ Let the distance from the roller to the left edge of the distributed load be $\backslash ($ d$\_\{1\}=0\mathrm{.}6\backslash$mathrm$\{$~m$\}\backslash ).[$Hint: For this question, it is helpful to draw shear and bending moment diagrams. Use conventional coordinate directions: x is positive to the right and y is positive upward.$]$

Determine the normal force acting on the beam at point B$.$

Determine the shear force acting immediately to the left of point B$.$
