    - The graphical representation of variation of axial load on y axis and position of cross section along x axis is called as axial thrust diagram.

    - Bending moment is generally equal to zero at the point of contra-flexure.

    - The point of contra-flexure is useful to design reinforced concrete, structural steel beams, etc. It is the point where bending occurs and changes its sign from positive to negative or vice-versa.

    - Point of contra-flexure is a point where hogging of beam changes to sagging or vice-versa.
