To find a force's directional components that act along a cable and to find the coordinates
of a point on a cable that has a force vector applied to it.
three-dimensional cartesian force vectors are used throughout engineering mechanics
the generic force vector is represented as follows f f ,i+ j+f kwhere f is the
force vector and f, fy, and f. are the vector's i j and k components, respectively
the force vector has a magnitude f= f +f2 +f2 the vector's direction is
described by a unit vector u where u =f/f
part a
as shown a force vector f with a magnitude of c=190 lb is applied at point
components of f
and is directed toward point c. (figure 1) the distance
