$5-$ The rigid loaded beam is supported by the pin connection and the bar pinned to the beam.

All connections at $,$ and $$ are double$-$shear connections. If the allowable shear stress

for each of the $10-$mm$-$diameter steel pins is $=90$ MPa, and the allowable normal

stress for the $13-$mm$-$diameter rod is $=150$ MPa, determine the largest intensity $$ of

the uniformly distributed load that can be carried by the beam. $[2$ Marks$]$
