SUMMARY
The discussion clarifies the treatment of internal moments in mechanics of materials, specifically when analyzing elemental cubes or planar squares. It establishes that internal moments are not omitted due to cancellation but rather because they are a resultant of a distributed continuum of forces acting on the cut face. By representing these forces as a distribution rather than as a resultant, one can effectively simplify the analysis of normal, shear, and moment stresses.
