Part A. A rectangular beam is simply supported on two walls of $240\mathrm{mm}$ thickness and $6\mathrm{m}$ apart (centerto-center). The beam has to carry, in addition to its own weight, a distributed live load of $15\mathrm{kN}/\mathrm{m}$ and a dead load of $8\mathrm{kN}/\mathrm{m}$. Design the beam cross-section for the maximum moment at mid-span.
