Required information For a bolted assembly with N = 6 bolts, the stiffness of each bolt is kb = 1 Mlbf/in and the stiffness of the members is km² 20 Mlbf/in per bolt. A repeated external load of W= 72 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use ½ in-13 UNC grade 8 bolts with rolled threads. Assume the bolt are preloaded to 75 percent of the proof load and the external load is a repeated load. Number of Bolts, N Bolt Grade, G Bolt Diameter, d 6 SAE 8 1/2 in termine the fatigue factor of safety for the bolts using the Goodman failure criterion. e fatigue factor of safety for the bolts using the Goodman failure criterion is
