The mor e held In) and is subject to and in the figure the n -14UN 2 the member 2. The nonpermanent bolted connection shown in the figure uses SAE grade 5 bolt (7/8 in-14 UNF x 2% in) and is subject to a static tension load of F - 20 kip. The bolt stiffness is 5 x 10 lbf/in, the member stiffness is 8 x 10° lb/in. Determine factors of safety against connection failure. (30 points)

12. A M 116*2 SAE grade 8.8 bolt is subject to a cyclic stress. The minimum nominal stress in the tensile area is calculated to be 200 Mpa (corresponding to its initial tension with no external load) and maximum nominal stress is 400 Mpa (corresponding to maximum external load). Determine the factor of safety guarding against eventual fatigue failure for this bolt. a. 0.85 b. 1.15 C. 1.65 d. 1.82 e. None of these

The figure illustrates the nonpermanent connection of a steel cylinder head to a grade 30 cast-iron pressure vessel using Nbolts. A confined gasket seal has an effective sealing diameter D. The cylinder stores gas at a maximum pressure Pg. For the specifications given in the table for the specific problem assigned, select a suitable bolt length, assuming bolts are available in increments of 5 mm. Then determine the yielding factor of safety np. the load factor nu and the joint...

A 1/2-13 UNC-2A grade 5 bolt is to be used as a fastener in a connection. The bolt will be loaded to 80 % of its proof strength. The bolted joint has a joint constant of C = 0.21. A load of P = 8400 lbs is applied to the bolted joint. Determine the factor of safety in the bolt using the Proof Strength as the failure strength. Express your answer to exactly one decimal place. Answer must be 1.4
