M16x2 grade 8.8 bolts No. 25 C1- Q.2. The figure is a cross section of a grade 25 cast-iron pressure vessel. A total of N, M16x2.0 grade 8.8 bolts are to be used to resist a separating force of 160 kN. (a) Determine ks, 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 19 mm is taken apart. (c) with the number of bolts obtained in (b), determine the realized load factor for overload, the yielding factor of safety, and the separation factor of safety. 19 mm

Problem4. The thin uniform disk of mass m = 1-kg and radius R = 0.1m spins about the bent shaft OG with the angular speed w2 = 20 rad/s. At the same time, the shaft rotates about the z-axis with the angular speed 001 = 10 rad/s. The angle between the bent portion of the shaft and the z-axis is ẞ = 35°. The mass of the shaft is negligible compared to the mass of the disk. a. Find the angular momentum of the disk with respect to point G, based on the axis orientation as shown. Include an MVD in your solution. b. Find the angular momentum of the disk with respect to point O, based on the axis orientation as shown. (Note: O is NOT the center of fixed-point rotation.) c. Find the kinetic energy of the assembly. z R R 002 2R x Answer: H = -0.046ĵ-0.040 kg-m²/sec Ho=-0.146-0.015 kg-m²/sec T 0.518 N-m =
