A steel strut S serving as a brace for a boat hoist transmits a compressive force P = 57 kN to the deck of a pier as shown in the figure. The strut has a hollow square cross section with wall thickness t = 9 mm and the angle θ between the strut and the horizontal is 51°. 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 = 15 mm, the thickness of the gussets is tG = 12 mm, the thickness of the base plate is tB = 10 mm, and the diameter of the anchor bolts is dbolt = 12 mm. Determine the bearing stress between the anchor bolts and the base plate in MPa.
