The figure gives the cross-section of a grade 25 cast-iron pressure vessel. A total of N bolts are to be used to resist a separating force of 150 kN.  (a) Determine kb, km, and C.  (b) Find the number of bolts required for a load factor of 2 where the bolts may be reused when the joint is taken apart.   (c) With the number of bolts obtained in part (b), determine the realized load factor for overload, the yielding factor of safety, and the load factor for joint separation. Use (SI) units as it applies
