More generally it may be stated that the change in shear force between any two sections of a beam is equal to the total load between those sections. ... Hence the area of the shear force diagram from Ai to Xi is equal to the bending moment at X. This is true only when the ... moment may be used to derive shear force and bending moment diagrams, as illustrated in the worked examples which follow.
