. The steel strut transmits a compressive force P = 72 kN as shown in the figure. The strut has a hallow cross section with a thickness of 12 mm , and the angle between the strut and the horizontal plane is 0 = 40°. A 16-mm-diameter pin through the strut transmits the compressive force to two gussets that are welded to the base plate. Four 20-mm-diameter bolts anchors the plate to concrete. The thickness of the gusset is 12 mm and the thickness of the base plate is 18 mm. Calculate the bearing stress (MPa) between the bolt and the base plate.

Transcribed Image Text:25. The steel strut transmits a compressive force P = 72 kN as
shown in the figure. The strut has a hallow cross section with
a thickness of 12 mm, and the angle between the strut and the
horizontal plane is 0 = 40°. A 16-mm-diameter pin through
the strut transmits the compressive force to two gussets that
are welded to the base plate. Four 20-mm-diameter bolts
anchors the plate to concrete. The thickness of the gusset is
12 mm and the thickness of the base plate is 18 mm. Calculate
the bearing stress (MPa) between the bolt and the base plate.
Neglect friction between the base plate and the concrete base.
