A 1-in-diameter hot-rolled AISI 1144 steel rod is hot-formed into an eyebolt similar to that shown in the figure for Prob. 3–74, with an inner 2-in-diameter eye. The threads are 1 in-12 UNF and are die-cut. (a) For a repeatedly applied load collinear with the thread axis, using the Gerber criterion is fatigue failure more likely in the thread or in the eye? (b) What can be done to strengthen the bolt at the weaker location? (c) If the factor of safety guarding against a fatigue failure is nf = 2, what repeatedly applied load can be applied to the eye?
Answer to relevant QuestionsThe section of the sealed joint shown in the figure is loaded by a repeated force P = 6 kip. The members have E = 16 Mpsi. All bolts have been carefully preloaded to Fi = 25 kip eachThe figure shows a bolted lap joint that uses SAE grade 8 bolts. The members are made of cold-drawn AISI 1040 steel. Find the safe tensile shear load F that can be applied to this connection if the following factors of ...A split-ring clamp-type shaft collar such as is described in Prob. 5–31 must resist an axial load of 1000 lbf. Using a design factor of n = 3 and a coefficient of friction of 0.12, specify an SAE Grade 5 cap screw using ...Given the following functions F(s), find f (t), F(s) = 4/(s + 1) + (s + 2) F(s) = 10s/(s + 1) + (s + 4)Given the following functions F(s) find f(t) F(s) = 6s + 12 / (s2 + 4s +5) (s2 + 4s +8) F(s) = s(s + 2) / (s2 + 2s + 2)
