Hello all,

can someone post a worked example of a trunnion calc according to the Kellogg method (subject 3810)which includes axial/longitudinal&circumferential (thermal)forces.????

i have a copy of this paper but i am confused about the following:

1.does table A apply to cylindrical attachments?
(i believe this is NOT the case and that f is independant of any factors)

2.What is the correct way of combining axial/longitudinal/circumferential stresses as calculated?
3.how do we include the pressure stresses whith all 3 stresses in operation.


Every spreadsheet i have come across has a different take on this.


your comments are appreciate
