The bending moment, axial force and shearing force are defined for a given
point P on the curved beam, positioned at an angle measured radially from
point 1, as shown in Fig. 1.22, namely:

The direction of the axial force N is the tangent axis at P, whereas the
direction of the shearing force S is the normal (radial) axis in Fig. 1.22.
Equations (1.124), (1.125) and (1.126), combine into:
