A single-cylinder engine head sees forces that range from 0 to 4000 lbs each cycle. The piston is 3 in dia and the cylinder is 5.5 in outside dia. The engine head is permanently fastened with 8 steel bolts of 5/16-18 UNC, Grade 5 that are located around a circle of diameter 4.25 inches. You assistant calculated the bolt and member stiffness values to be 457.3 and 2345 kip/in respectively.(a) Calculate the bolt tightening torque if they are lubricated.(b) Calculate the alternating and mean stresses per bolt.(c) Calculate the Goodman fatigue safety factor if corrected fatigue strength for the bolt material Se
