Using equation $(1-4)$ of the text, $F=q_{h}G{C}_f{A}_s,$ determine the resultant force, in kips, acting on the face of the billboard if $q_h=32l\frac{b}{f}{t}^2.$ The dimensions of this sign are indicated. Assume $\frac{B}{s}=4$ Vn should interpolate.

$($c$)29\mathrm{.}23$

$($d$)33\mathrm{.}41$

Classify the structure below. It has a roller each at $B$ and $C,$ as well as a fixed end

$($a$)$ Unstable

$($b$)$ Statically determinate

$($c$)1$st degree statically indeterminate

$($d$)$ None of the other three choices

For a classroom in a school as shown below, determine the live load for design in pounds per square foot of floor area if no reduction needs to be made.

$($c$)100$

$($d$)125$
