Answer to: Uses of Shear Force and bending Moment Diagram
Purpose of  Shear Force and bending Moment Diagram

1. We can use a shear force diagram to analyze the beam
2. The shear force diagram indicates the shear force resisted by the beam section along the length of the beam.
3. The bending moment diagram indicates the bending moment resisted by the beam section along the length of the beam.
4. Shear and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear force and bending moment  at a given point of an element.
5. Using these diagrams the type and size of a member of a given material can be easily determined.
6. Another application of shear and moment diagrams is that the deflection can be easily determined using either the moment area method or the conjugate beam method.
