Qualitative shear and moment diagrams
What is an inflection point (or point of contraflexure)? Where does it occur in the beam?
Inflection point (or point of contraflexure) is the point in the beam where the moment diagram changes sign (from + to - or vice versa) and is the point where the deflection curve changes the direction of curvature.
