An M30 × 3.5 ISO grade 8.8 bolt is used in a joint at a preload level recommended for reused connections, and the joint is subject to a repeated tensile fatigue load of P = 65 kN per bolt. The joint constant is C = 0.25. Determine the static load factors; [12 pts.] The factor of safety guarding against a fatigue failure based on the Goodman fatigue criterion. [18 pts.]

The question is to estimate the maximum value of F that would
not cause eventual fatigue failure of the bolts. Given that SAE
CLASS= 8.8 , D= 24 mm, SF=2
Two bolts with rolled threads (see table 10.6 of the textbook), are used to attach a pillow block, as shown in the figure below. Please select the grade (SAE Class) and the size of the bolts (nominal diameter) from the table (see next page) and refer to the tables 10.5...

[3]. (3 marks) Figure below shows a bolted joint subjected to an external force P that fluctuates from 0 to 7 kips The steel bolt specification is 5/8"-11 UNC, SAE grade 5 material with rolled threads. The clamped members are steel of length 1.25 in each (with a total length of 2.5 in). Plain wide washers are utilized at both ends of the bolt. [a]. Using the Goodman line, determine the factor of safety guarding against fatigue failure for the...
