A T$-$Section beam having flange $2$ cm x $10$ cm and web $10$ cm x $2$ cm is simply supported over a span of $6$ m$.$ It carries a U$.$D$.$L$.$ of $3$ kN$/$m run including its own weight over its entire span; together with a load of $2\mathrm{.}5$ kN at mid span. Find the maximum tensile and compressive stresses occurring in the beam section.
