Question $1$: A beam with the cross$-$sectional geometry depicted in the figure is subjected to a bending moment of $\backslash (20\backslash$mathrm$\{$kN$\}\backslash$cdot $\backslash$mathrm$\{$m$\}\backslash ).$ The moment acts in the direction indicated in the figure. Determine:

a$)$ The stress value at point A on the cross section.

b$)$ The position and orientation of the neutral axis, including its representation on a sketch of the cross section.

c$)$ The maxiumum tensile stress and compressive stress within the beam.
