Hi there:
Im trying to determine the force to torque relationship for a bolted surface. This surface should maintain a certain pressure (e.g. 8000 psi). Usually 4 bolts are used, so i determined the axial force needed from each bolt. My problem is how to determine how much torque needed to reach that axial force. I have found T=K*D*F and also another equation used in power screws that involves picth angles. I would apreciate any help with this.
Also bolt material is stronger that taped surface (Bolt= Stainless steal 35 ksi; Surface: Aluminum T6-6061 32 ksi) can I make the same analysis on the aluminum as the one i used for the bolt?
Thanks
Rudy
