In problem $1,$ the objective of this problem is to calculate the normal stress in beam $D$ from axes $3$ to $4,$ which is illustrated in Fig. $1.$ Consider the following data.

The slab and beams are made of reinforced concrete

The concrete's volumetric weigh is $23\mathrm{.}6\frac{KN}{m^2}$

The slab is $0\mathrm{.}2m$ thick

The additional service dead load of the slab is $1\mathrm{.}2\frac{KN}{m^2}$

The beams running in the $x$ direction are $0\mathrm{.}3m$ wide and $0\mathrm{.}45m$ depth

The building is use for office space, with a service life load of $2\mathrm{.}4\frac{KN}{m^2}$

The factored load is defined by $U=1\mathrm{.}20+1\mathrm{.}6L$

Answer to the following question:

Q$2.$ What is the factored beam load in$\frac{KN}{m}$ for beam D$3-$D$4(1$ point$)$
