Shear and moment diagram
Shear and Moment Diagrams
Shear and bending moment diagrams are analytical tools used in structural analyses and structural design to determine the value of shear force and bending moment at different length of an element. Using these diagrams type and size of a member can be determined easily. 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.
