The cover of a cylindrical pressure vessel made of cast iron is shown in fig.1 The inner diameter of the cylinder is 500 mm and the internal pressure is limited to 2MPa. The cover is fixed to the cylinder by means of 16 bolts with a nominal diameter of 20 mm. Each bolt is initially tightened with a preload of 20 KN. The bolts are made of steel FeE250 (S yt = 250 N/ mm 2 ). Assume. E for steel = 207 KN/mm 2 ,E for cast iron = 100 KN/mm 2, E for Zinc = 90 KN/mm 2,Determine the factor of safety for bolts considering the effect of the gasket.
