Webb8 dec. 2011 · Consequently, it is not always sufficient to investigate the points of zero shearing force when determining the maximum bending moment. At a point on the beam where the type of bending is changing from sagging to hogging, the bending moment must be zero, and this is called a point of inflection or contraflexure.
