Action-reaction-resultant:
“Engineers are always talking about action and reaction, but they oversimplify. We have reaction and action, but we also have resultants; and every event, then, is really a three-part affair.” I find that the resultant and the reaction are never at 180 degrees, which is an approximate figure as there are always some odd angles.
“Reactions and resultants are always precessional.”
