For a bolted assembly with six bolts, the stiffness of each bolt is kb = 2.5 Mlbf/in and the stiffness of the members is km = 10 Mlbf/in per bolt. A repeated external load of 60 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 3/8 in-16 UNC grade 8 zinc-plated bolts, #2 fit, with rolled threads and regular hexagonal nuts. Assume the bolts are preloaded to 75 percent of the proof load.(a) Determine the yielding factor of safety.(b) Determine the overload factor of safety.(c) Determine the factor of safety baserd on joint seperation.
