Please answer the following for the beam shown below:

a$)(10$ pts$)$ Calculate the shear demand $(\frac{V_u}{})$ at the face of the left column $(($:$x=0ft\},$ at $d$ from the face of the support, and at midspan. Consider pattern loading. Plot $\frac{V_u}{}$ versus $x$ for the left half of the span.

b$)(10$ pts$)$ Where $($for what $x)$ are stirrups not required?

c$)(10$ pts$)$ Select a $2-$leg stirrup size and spacing that satisfies requirements for minimum area and maximum spacing. Select the largest permissible integer spacing.

d$)(10$ pts$)$ Can the stirrups selected in $($c$)$ be used throughout the span? In other words, is the nominal shear strength greater than the controlling $\frac{V_u}{}?$

e$)(5$ pts$)$ How far from the face of the column should the first stirrup be placed?

$f_c^{\text{'}}=4000$

$f_y=60$ksi

$b_w=14in.$

$h=24in.$

$h_{\text{s}\text{l}\text{a}\text{b}}=5in.$

Length $=28ft$

$l_n=26ft$

Normal$-$weight concrete with: $d_{\text{a}\text{g}\text{g}}=1$ in$.$

Clear cover to stirrup: $c_c=1\mathrm{.}5in.$

Unfactored live load: $w_L=1\mathrm{.}5\frac{k}{f}t$

Unfactored dead load: $w_D=0\mathrm{.}9\frac{k}{f}t$
