Text: "Cancellation of internal forces." Involves difference between resultant of forces and sum of forces. Internal forces occur in equal and opposite pairs, so that they contribute nothing to the sum. Pursuing this difference leads to the new scalar stress electromagnetics, because the internal forces create spatiotemporal stress and anenergy. American Journal of Physics. 49(4), Apr. 1981. p. 372.
