Using 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 constants are C = 0.30 for coarse- and 0.32 for fine-thread bolts.
Answer to relevant QuestionsAn M30 X 3.5 ISO 8.8 bolt is used in a joint at recommended preload, and the joint is subject to a repeated tensile fatigue load of P = 80 kN per bolt. The joint constant is C = 0.33. Find the load factors and the factor of ...The bolted connection shown in the figure is subjected to a tensile shear load of 20 kip. The bolts are SAE grade 5 and the material is cold-drawn AISI 1015 steel. Find the factor of safety of the connection for all possible ...A 3/8 – x 2-in AISI 1018 cold-drawn steel bar is cantilevered to support a static load of 300 lbf as illustrated. The bar is secured to the support using two ½ in-13 UNC SAE 5 bolts. Find the factor of safety for the ...Given the following functions F(s), find f (t). F(s) = s2 + 5s + 4 / (s + 2) (s + 4) (s + 6) F(s) = (s + 3) (s + 6) / s (s2 + 8s + 12)Given the following functions F(s), find f(t) F(s) = s + 8 / s2 (s + 62) F(s) = 1 / s2 (s + 1)2
