steel strut S serving as a brace for a boat hoist transmits a compressive force P = 63 kN to the deck of a pier as shown in the figure. The strut has a hollow square cross section with wall thickness t = 8 mm and the angle θ between the strut and the horizontal is 41°. A pin through the strut transmits the compressive force from the strut to two gussets G that are welded to the base plate B. Four anchor bolts fasten the base plate to the deck. The diameter of the pin is dpin = 19 mm, the thickness of the gussets is tG = 14 mm, the thickness of the base plate is tB = 10 mm, and the diameter of the anchor bolts is dbolt = 10 mm. Determine the bearing stress between the anchor bolts and the base plate in MPa.
