are the resultant and moment resultant of the inner forces acting on a cross section. The bending moment is positive if its vector points in the positive y direction, the shear force is positive if it points in the negative z direction—see Fig. 7.8 for details. With Eq. (7.2a) yields

As regards Eq. (7.2a), we may write
