$engineering mechanics statics force along a direction$

When a beam or frame is subjected to transverse loadings, the three possible internal forces that are developed are the normal or axial force, the shearing force, and the bending moment, as shown in section k of the cantilever of the figure below. This is for a 2d analysis of the beam assuming there is negligible loading in the third dimension.

The shear force for a column would be horizontal and is sometimes called ‘transverse’.

For this reason, the normal force is often called ‘axial’ as in: along the axis. Note that for a vertical column, the normal force would be vertical. The following table summarizes information on internal forces (and moments). Normal and shear have units of N or lb and bending moment has units of Nm or ft-lb. Shear force, the vertical force is represented with ‘V’. bending moment (M) – changes based on the applied loads and applied moments.shear force (V) – the vertical force that changes based on the applied loads.normal force (N) – the horizontal force we calculated in trusses in the last chapter.There are 3 types of internal forces (& moments): Adapted from source: Engineering Mechanics, Jacob Moore, et al. When you make a cut in an object, similar to a fixed reaction, we describe what is happening at that point using one horizontal force (called normal force), one vertical force (called shear force), and a bending moment.
