the particle at D ; and it is evident that we may suppose DK to be infinite, because the action of the points situated beyond K are supposed to be insensible on the particle at D ; therefore the whole action of the body, upon the particle at D, will be represented by r?°p.(/s.n(s) in the direction… … P; lids r=^; ddx 1^~ ^ dts P, Q [34], being the forces acting upon the particle in the directions parallel to the rectangular co-ordinates x, s, respectively, and tending to increase the co-ordinates [34^]. In the present case, the only force acting upon the particle is that in [8158A], which is…
