A cantilever I beam has a cable at end B that supports a force . and
is the position vector from end . I of the beam to end B. Position vectors
and
, are parallel to the flanges and web of the I beam, respectively. For determination of the internal forces in the beam (discussed in Chapter 8). and for mechanics of materials analysis, it is necessary to know the components of the force in the axial direction of the beam (AB) and in directions parallel to the web and flanges.
Determine the scalar and vector components of in direction
.
