A short column with a wide$-$flange shape is subjected to a compressive load that produces a resultant force $P=26\mathrm{.}3kN$ acting at the midpoint of one flange $($see figure$).$

$$

$($a$)$ Determine the maximum tensile and compressive stresses ${}_t$ and ${}_{c^{\text{'}}},$ respectively, in the column. $($Enter your answers in MPa. Use the deformation sign convention.$)$

$($b$)$ Locate the neutral axis under this loading condition. $($Enter the value of $y,$ in mm $,$ on which this axis lies.$)$

$($c$)$ Recompute maximum tensile and compressive stresses if a $120mm10mm$ cover plate is added to one flange as shown. $($Enter your answers in MPa. Use the deformation sign convention.$)$
