    Constraining rotation of primary datum axis with a secondary orthogonal datum axis

    Morning all, Hoping for some input/feedback on whether or not an orthogonal datum axis feature can be used to constrain the rotation of a primary datum axis. I can't find an example of this scenario in Y14.5-2009 or in any other online resources. The closest reference I could find was section...

    Hello all, I'm looking at the stresses generated in a hub due to press fitting on a shaft or due to an internal keyless locking assembly (such as from Ringfeder, B-Loc, Bikon etc). I'm wondering if exceeding the yield strength of the hub material at the contact interface (i.e. hub ID/shaft OD)...
