Complete the ULS component of flexural design for the critical section $($i$.$e$.,$ where moments are greatest$)$ in the cantilever beam illustrated in the following figure. Without calculations, where will the rebars be placed for such a beam?

Cover: governed by requirements in Table $17$ in CSA A$23\mathrm{.}3$:$24$

Concrete: compressive strength of $40$ MPa to satisfy durability requirements. Concrete is normal density $\backslash (\backslash$left$(24\backslash$mathrm$\{$kN$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash$right$)\backslash )$ with a maximum aggregate size of $19$ mm $.$

Reinforcement: Grade $400$ steel $\backslash (\backslash$left$($f$\_\{$y$\}=400\backslash$mathrm$\{$MPa$\},$ E$\_\{$s$\}=200\backslash$mathrm$\{$GPa$\}\backslash$right$)\backslash ).$ For constructability, the largest available bars for this beam are $30$ M $.$ Assume stirrups are $10$ M $.$

Other constraints and information:

$-$ Remember to account for beam self$-$weight.

$-$ You are not required to check deflections if the beam satisfies conditions of Table $9\mathrm{.}2$ of CSA A$23\mathrm{.}3$:$24.$

$-$ You do not need to design for shear as part of this question.

Specified live load: $\backslash (11\backslash$mathrm$\{$kN$\}/\backslash$mathrm$\{$m$\}\backslash )$

Sunerimoosed Dead Load: $\backslash (6\backslash$mathrm$\{$kN$\}/\backslash$mathrm$\{$m$\}\backslash )$
