4) Apply N internal forces (actually torsions) to
reverse the incompatible deflections
5) Add #2 and #4(s) to get the solution
The above steps are sketched below;
The cuts and the slip at the cuts are in the
longitudinal direction;
The shear flow occurs on the cross section, which
is a transverse vertical plane. The shear stresses
on this plane will also occur on a longitudinal
plane at right angles to the transverse plane. The
longitudinal plane may be horizontal or vertical or
inclined. The stressed plate will respond to the
shear by distorting into a 'diamond' with relative
movement in the longitudinal direction, which
creates a differential slip over a small part of the
cross section.
