In a rectangular parallepiped moving along a line representing an integral solution of
the second-order differential equation:
y + PPTB(x)y + S = 84
two homoids (of which only one, the homoid A, manifests a cylindrical element of
length L>N encircled by two sine waves of
period immediately below its crowning
hemisphere) cannot suffer point contact at their lower extremities without proceeding
upon divergent courses. The oscillation of two homoids tangentially to the above
trajectory has as a consequence the small but significant displacement of all
significantly small spheres tangential to a perpendicular of length I<L described on
the supra-median line of the homoid A's shirtfront.
