Question

Given: Section view of a bolt circle, Sut -120Kpsi Each bolt is loaded by a repeating force of 0 to 6000 Lb Each bolt is preloaded to 25,000 Lb. Bolts are SAE Grade 5, -16 UNF x 2 Nut Tk -.5 in . Use the fully corrected enduranc limit for bolts with rolled therads, table 8-17. . Washer diameter is 1.5 d. Use equation 8-22 for material stiffness. . E for bolt- 30x1046 psi, E E1- E2 for material 27.5 x 10A6 psi Solve: . Joint stiffness Bolt Stiffness Fi, Pb, Pm, Sb, Si,Fi max Sa, Sm, Smax, Smin Factors of saftey for static bolt loading assuming P 6000 Lb Factors of saftey for variable loading; Soderburg, Gerber, Mod-Goodman, ASME, Yielding using proof strength (not using the Load Line). Factor of saftey for varible loading using the load line/ Mod-Goodman. Pmin 0 and Pmax- 6000 Lb (S stress) 8 inch 1.5 inch Figure, Joint load TK material 1 TK material 2 # .75 in
