Question $3(25$ marks$)$

A simply supported beam carries a uniformly distributed $10ad$ of $20k\frac{N}{m}$ and two points load, $40kN$ each, as shown in Figure $Q_3(a).$ The beam section is shown in Figure $Q_3(b).$ Use the following parameters: Estecl $=200$GPa. Econcrete $=20$GPa. $|$s$|$steel section$)=195{10}^{6}m{m}^4,A_{\text{s}\text{t}\text{e}\text{e}\text{l}}=8\mathrm{.}55{10}^{3}m{m}^2,$ lc$|$concrete sectionl $=562\mathrm{.}5{10}^{6}m{m}^4.$ Aconcrete $=300{10}^{3}m{m}^2,$ Nbotiom $=432mm$
