Current Topic:
Press Fit Pressure
Neil,
I finally got around to trying to digest this.  Everything seems to be in order, but I have a few questions.  I'm looking at the part of your explanation that states:

Since there are no applied external forces, the sum of the internal forces must = 0

Or the ((stress in steel x area) + (stress in copper x area)) = 0


What areas are you referring to?  A cross sectional area?  The reason I ask this is because you take the length as cancelling out (which makes sense - the press fit causes the same length on each piece), but why the thicknesses?  I would think you'd use surface are contact here?

Thanks for explaining....I appreciate all your help

Dan
