conditions for beams $($b$).$

Figure $2.$ Load bearing structural members and loadings.

Label the load bearing structural members. Illustrate

the loads acting on the structural members as shown in

the Figure $2.$

Select one of the roof beams and check the safety of

the beam. In this example roof beam $2$ has been

selected. If the cross$-$sectional dimensions of the

selected beam is not given, select a cross$-$section for

the beam.

Load acting on the roof can ben taken as $p=1\mathrm{.}50k\frac{N}{m^2}$

If the span length of the Beam $2$ is selected as $L=5m,$

then what is the load acting on the beam? Why is it $3$kNm$?$ Can you explain?
