Definition of Shear Force and Bending Moment Shear force is taken ve if it produces a clockwise moment and it is taken ve when it produces an anticlockwise moment. Bending moment at any point along a loaded beam may be defined as the sum of the moments due to all vertical forces acting on either side of the point on the beam.
At any point within a beam, the Bending Moment is the sum of: each external force multiplied by the distance that is perpendicular to the direction of the force. Shearing Force The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion.

APPLICATION OF SHEAR FORCE AND BENDING MOMENT: One of the most significant applications of shear force and bending moment diagram is that we can calculate how much area of steel is required for the section of the structural member while designing any of the structural members such as beam, column or any other member.
Shear force is taken ve if it produces a clockwise moment and it is taken ve when it produces an anticlockwise moment. Bending Moment – Bending moment at any point along a loaded beam may be defined as the sum of the moments due to all vertical forces acting on either side of the point on the beam. The bending moment tries to bend the beam.
After the support reactions are calculated, the shear force and bending moment diagrams can be drawn. Shear force is the force in the beam acting perpendicular to its longitudinal (x) axis. For design purposes, the beam's ability to resist shear force is more important than its ability to resist an axial force.
Shear force is basically defined as the algebraic sum of all the vertical forces at any section of the beam either left hand side or right hand side of the section. Shear force is also a type of force and hence its unit will be Newton.
