<P> 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 a structural element such as a beam . These diagrams can be used to easily determine the type, size, and material of a member in a structure so that a given set of loads can be supported without structural failure . Another application of shear and moment diagrams is that the deflection of a beam can be easily determined using either the moment area method or the conjugate beam method . </P> <P> Although these conventions are relative and any convention can be used if stated explicitly, practicing engineers have adopted a standard convention used in design practices . </P>
