The upper deck of a football stadium is supported by braces, each of which transfers a load P=150 kips to the base of a column (see figure part a). A cap plate at the bottom of the brace distributes the load P to four flange plates (t=1 in.) through a pin (dp=2 in.) to two gusset plates (t = 1.5 in.) (see figure parts b and c). Determine the following quantities: (a) The average shear stress in the pin (b) The average bearing stress between the flange plates and the pin, and also between the gusset plates and the pin. Note: Disregard friction between the plates.

![The upper deck of a football stadium is supported by braces, each of which
transfers a load P = 150 kips to the base of a column (see figure part a). A cap plate at the bottom
of the brace distributes the load P to four flange plates (t-1 in.) through a pin (d, = 2 in.) to two
gusset plates (t = 1.5 in.) (see figure parts b and c).
Determine the following quantities:
(a) The average shear stress in the pin
(b) The average bearing stress between the flange plates and the pin, and also between the gusset
plates and the pin
