When three forces having the same point of application do not lie in the same plane, the resultant is the diagonal of the parallelopiped formed on these forces as edges.

Suppose the three forces are P, Q, and S (Fig. 1). The resultant of P and Q is R' in the plane  ABEC, while the diagonal AH is the resultant of R' and S in the plane AEHD, and is the required resultant.
