Adapter stress estimates

Stresses are computed for the 0.320 neck region.

Pressure stress (psi)

Assume the pressure operates at crushwasher ID = 0.379 dia
Assume stress concentration factor = 2.0 from Shigley, 7th Edition, Figure A-15-7
(D/d = 1.75, r/D = 0.125)

Torque shear stress at 0.320 diameter (σθz)

Use ANSI B1.1 C.3.2

Torque axial stress at 0.0320 diameter (σzz2)

Assume Equation 8-27, Shigley, Seventh Edition

25 g vibrational stress, axial and bending stress (σzz)

There is no bending stress if the adapter remains tight.  However, bending stress is calcualted asuming
adapter is loose for worst case scenerio. Assume entire weight = 0.2 lb acts at 1 inch from neck

These reactions are insignificant compared to previous calcuated reaction forces.

Compute von mises stress

The computed max Mises stress is 68 ksi.
