Illustration used "If three component motions ab, ac, and ad are combined, their resultant af will be the diagonal of the parallelopiped of which they are the edges."

Parallelopiped of Motions

Illustration used "If three component motions ab, ac, and ad are combined, their resultant af will be…

Illustration "where ad is the given resultant, if the two components have the magnitudes represented by ac and ab, the directions ac and ab would solve the problem, or the direction ac<sub>1</sub> and ab<sub>1</sub> would equally well fulfil (sic) the conditions."
