Lateral bracing for an elevated pedestrian walkway is shown in the figure part (a). The thickness of the clevis plate tc = 16 mm and the thickness of the gusset plate tg = 20 mm [see figure part (b)]. The maximum force in the diagonal bracing is expected to be F = 190 kN.
If the allowable shear stress in the pin is 90 MPa and the allowable bearing stress between the pin and both the clevis and gusset plates is 150 MPa, what is the minimum required diameter dmin of the pin?
