A Beam is defined as a structural member subjected to transverse shear loads during its functionality. Due to those transverse shear loads, beams are subjected to variable shear force and variable bending moment.
Shear force diagram and bending moment diagrams are illustrations to describe the alterations in shear force and bending moments over the length of the beam. These diagrams can be utilized to analyze the failure of the structure with the given inputs like loads, structure material, and shape. Hence, SFD and BMD reduce the probability of the structure’s failure. Also with the implementation of the conjugate beam method or moment area method, the deflection of the beam can be resolved.
