against the hands of a watch; as nega-tive when with the hands of a watch.* Hence, in general, the resultant of any two parallel forces is,in amount, equal to their algebraic sum, acts in a parallel direc-tion in the same plane, while its moment, about any arbitrarypoint in the plane, is equal to… … Fig. 12. Fig. 13. (using the notation of Fig. 12), we have Pa sec a = PxO-\ sec a-\-P^^ sec a, i.e., Pb = Pibi+P2b2,in which b, bi and bi are the oblique distances of the threelines of action from any point 0 in their plane, and Ke on thesame straight line; P is the resultant of the parallel forces…
