I was checking to see was it possible to determine the bending moment diagram from the shear force diagram.

Seemingly one can do it for simply supported beams but if we consider a rigidly supported beam on either end its not possible to derive the bending moment diagram from the shear force diagram.

Can anyone confirm this is true?

See attached schematic of a simply and rigidly supported beams.
