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

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

for each of the $10-mm-$diameter steel pins is ${}_{\text{a}\text{l}\text{w}}=90$MPa, and the allowable normal

stress for the $13-mm-$diameter rod is ${}_{\text{a}\text{l}\text{w}}=150$MPa, determine the largest intensity $w$ of

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