$(25\%)$ Problem $4$:

For the "light manufacturing" structure shown in Figure, assume that the dead load consists of

the reinforced concrete floor structure and superimposed dead load of $40$ psf in addition to the

live load $($Check Table $1607\mathrm{.}1$ IBC $2018).$ The weight of the reinforced concrete can be taken as

$150$ pcf$.$ Find the distributed "design" load on a typical beam $[$as highlighted in Figure $($a$)].$

Sketch the FBD of the typical beam.
