The Shear Force at any point along the beam is the total forces acting perpendicular to beam longitudinal axis up to the point. The bending moment at any point along the beam is equal to the area under the shear force diagram up to that point. (Note:

Abstract—Recently, a 3D face recognition approach based on geometric invariant signatures, has been proposed. The key idea of the algorithm is a representation of the facial surface, invariant to isometric deformations, such as those result
