Required information For a bolted assembly with 19 bolts, the stiffness of each bolt is kh= 1.0 MN/mm and the stiffness of the members is km = 2.6 MN/mm per bolt. The bolts are preloaded to 75 percent of proof stiffness. Assume the external load is equally distributed to all bolts. The bolts are M6 × 1 class 5.8 with rolled threads. A fluctuating load is applied to the entire joint with Wmax = 60 kN and Wmin = 20 kN. The bolt diameter is d= 6 mm.

For a bolted assembly with 19 bolts, the stiffness of each bolt is kp = 1.O MN/mm and the stiffness of the members is km=
2.6 MN/mm per bolt. The bolts are preloaded to 75 percent of proof stiffness. Assume the external load is equally
distributed to all bolts. The bolts are M6 x 1 class 5.8 with rolled threads. A fluctuating load is applied to the entire joint
with Wmax = 60 kN and Wmin = 20 kN. The bolt diameter is d= 6 mm.
