A $16 \: mm$ thick gusset plate is connected to the $12 \: mm$ thick flange plate of an I-section using fillet welds on both sides as shown in the figure (not drawn to scale). The gusset plate is subjected to a point load of $350 \: kN$ acting at a distance of $100 \: mm$ from the flange plate. Size of fillet weld is $10 \: mm$.

The maximum resultant stress (in MPa, round off to $1$ decimal place) on the fillet weld along the vertical plane would be _______
