Q$2(5$ Points$)$: The cantilever RC beam shown in figure $($Span $L$ is given for each student$),$ carries service triangular live load $($maximum value W$1$ is given for each student$)$:

$$ Find the dead load of the RC beam. Note: Consider the dead load as uniformly distributed containing the beam's own weight only$)$

$$ Find the ultimate design shear value Vu$.($Note: Consider ultimate Vu at the support's center$)$

$$ Design the required shear reinforcement according to ACI$-318$ code. $($Note: Consider ultimate Vu at the support's center$)$

Use $F{c}^{\text{'}}=28$MPa,$Fy=420$MPa and $10mm$ stirrups

Wl$=70$

L$=1\mathrm{.}6$
