What is BMD and SFD

Question

What is BMD and SFD

Accepted Answer

BMD stands for bending moment diagram and SFD stands for shear force diagram.

BMD is a graphical representation of the variation of bending moment along the length of a beam.
SFD is a graphical representation of the variation of shear force along the length of a beam.
Both BMD and SFD are important tools in structural analysis and design.
BMD and SFD help engineers understand the internal forces and moments acting on a beam.
These diagrams are used to determine the maximum bending moment and shear force in a beam.
BMD and SFD are commonly used in civil and mechanical engineering.
Example: In a simply supported beam with a point load at the center, the BMD will be a parabolic curve with maximum bending moment at the center.
Example: In the same beam, the SFD will be a straight line with maximum shear force at the supports.
