The dynamic forces and moments arising from the motion of internal components in IC engines are known as Shaking Forces and Shaking Moments. These forces and moments are transmitted directly to the supporting structure, whether it be a concrete block or a ship's frame. They can cause significant damage if not properly evaluated at the design stage. It should be noted that these are inertial reactions only, and are unaffected by cylinder firing pressure. By a direct appeal to fundamental momentum principles, this paper presents an elegant and completely general approach to their determination, based on first principles. This is much simpler than the conventional direct approach through the piece-by-piece application of Newton's Second Law.
