Question $2(5$ points$)$

Two vertical forces are applied to the beam as shown. Determine $($a$)$ the maximum bending moment in $\backslash (\backslash$mathrm$\{$kN$\}-\backslash$mathrm$\{$m$\}\backslash )$ to two significant digits

$($b$)$ the value of the maximum bending stress in MPa to four significant digits. Identify tension with a positive value and compression with a negative value.
