CLASS: Engineering Mechanics: Statics     CHAPTER: Ch 2 Forces & Other Vectors
TOPIC: This video covers four topics: 1) how to compute a position vector from the coordinates of two points in three-dimensional space, 2) finding the unit vector of the position vector, 3) computing the components of a force vector sharing the same line, and 4) finding the direction cosine angles for the force vector. For an interactive version of this problem see https://www.geogebra.org/m/fab5kqxd
