Shear Force and Bending Moment Diagram - SlideShare Shear Force and Bending Moment Diagrams (SFD & BMD) 13. Point of Contra flexure [Inflection point]: It is the point on the bending moment diagram where bending moment changes the sign from positive to negative or vice versa. It is also called 'Inflection point'. At the point of inflection point or contra flexure the bending moment is zero. 14. How to calculate the Shear Force and Bending Moment Diagram? 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.
