6-4.4 Show the variation in the magnitude of the resultant of two vectors with a change in the angle between them on the overhead projector. Construction details in Appendix, p. 537. 1A40.41 resultant of vectors 6-4.7 Vector addition using elastic vectors on an open framework. An overhead projector device uses two compass needles to show that a vector remains invariant when displaced. Disc 01-05 Animation.
Animation shows vectors superimposed on a right hand.
