$l=360cm$

$R=16cm$

$h=150cm$

$F=403kN$

$($Force $F$ is parallel with the $xy$ plane. Point $Q$ is of $0\mathrm{.}8R$ distance from the beam axis.$)$

a$)$ Determine the internal force components at the section of the column next to the support and sketch them in a view opposite the arrow of axis $x.$

b$)$ Find normal and shearing stresses at point $Q$ of the cross section next to the support. Indicate the direction of shearing stress as well.

c$)$ Explain the steps of finding the direction of the shearing stress at point $A$ of the cross section. Show the steps in a freehand sketch.
