Importance of contraflexure
WitrynaConcept: The points of contraflexure (or inflection) are points of zero bending moment, i.e. where the beam changes its curvature from hogging to sagging. In a bending beam, a point of contraflexure is a location where the bending moment is zero (changes its sign). In a bending moment diagram, it is the point at which the bending moment curve ...
