Suppose the welded steel bracket shown in the figure is bolted underneath a structural-steel ceiling beam to support a fluctuating vertical load imposed on it by a pin and yoke. The bolts are ½ in coarse-thread SAE grade 5, tightened to recommended preload. The stiff nesses have already been computed and are kb = 4.94 Mlb/in and km = 15.97 Mlb/in.
Answer to relevant QuestionsUsing the Gerber fatigue criterion and a fatigue-design factor of 2, determine the external repeated load P that a 1 ¼ -in SAE grade 5 coarse-thread bolt can take compared with that for a fine-thread bolt. The joint ...A bolted lap joint using SAE grade 5 bolts and members made of cold-drawn SAE 1040 steel is shown in the figure. Find the tensile shear load F that can be applied to this connection if the following factors of safety are ...Find the total shear load on each of the three bolts for the connection shown in the figure and compute the significant bolt shear stress and bearing stress. Find the second moment of area of the 8-mm plate on a section ...Given the following functions F(s), find f(t) if F(s) = s + 1 / s(s + 2) + (s + 3) F(s) = s2 + s + 1 / s(s + 2) + (s + 1)Given following functions F(s), find f(t) F(s) = s + 1 / s2 (s+ 2) F(s) = s + 3 / (s+1)2 (s + 4)
