An angle bracket having thickness \( t=18 \mathrm{~mm} \) is attached to the flange of a column of two \( 14 \mathrm{~mm} \) diameter bolts (see figure). A uniformly distributed load from a floor joist acts on the top face of the bracket with pressure \( p=1.8 \mathrm{MPa} \). The top face of the bracket has length \( L=200 \mathrm{~mm} \) and width \( b= \) \( 75 \mathrm{~mm} \). Determine the average shear stress \( \tau_{a v g} \) in the bolts. Give your answer in MPa and to two decimal places.
