For a bolted assembly with eight bolts, the stiffness of each bolt is kb 5 1.0 MN/mm and the stiffness of the members is km 5 2.6 MN/mm per bolt. The bolts are preloaded to 75 percent of proof strength. Assume the external load is equally distributed to all the bolts. The bolts are M6 3 1 class 5.8 with rolled threads. A fluctuating external load is applied to the entire joint with Pmax 5 60 kN and Pmin 5 20 kN. (a) Determine the yielding factor of safety. (b) Determine the overload factor of safety.
