F1 ,..., F8 and M1,...,M4 are
applied to the end of a cantilever
beam as shown in the figure. (All
forces and couple moments are
parallel to one of the x, y or z axis.)
a) Replace F1 ,..., F8 and M1,...,M4 with an an equivalent
resultant force and resultant couple
moment at the center of the crosssection (G)
b)What are the coordinate direction
angles(alpha,beta and teta) of the resultant force.
