An angle bracket having a thickness t = 19 mm is attached to the flange of a column by two 16 mm diameter bolts (see figure). A uniformly distributed load from a floor joist acts on the top face of the bracket with a pressure p = 1.9 MPa. The top face of the bracket has a length L = 200 mm and width b = 75 mm.

Determine the average bearing pressure

_b
between the angle bracket and the bolts and the average shear stress t
_aver
in the bolts. Disregard friction between the bracket and the column.
