Link 2, shown in the figure, is 1 in wide, has 1 2 -in-diameter bearings at the ends, and is cut from low-carbon steel bar stock having a minimum yield strength of 24 kpsi. The end-condition constants are C = 1 and C = 1.2 for buckling in and out of the plane of the drawing, respectively.
(a) Using a design factor nd = 5, find a suitable thickness for the link.
(b) Are the bearing stresses at O and B of any significance?
