Draw SFD and BMD for a given beam?

Question

Accepted Answer

SFD and BMD are graphical representations of shear force and bending moment along a beam.

SFD (Shear Force Diagram) shows the variation of shear force along the length of the beam.
BMD (Bending Moment Diagram) shows the variation of bending moment along the length of the beam.
SFD and BMD are important tools in structural analysis and design.
They help in determining the maximum shear force and bending moment in a beam, which are crucial for selecting appropriate beam sizes and reinforcement.
SFD and BMD can be drawn by following the equilibrium equations and considering the applied loads, reactions, and support conditions.
The SFD and BMD diagrams typically have positive and negative regions, indicating tension and compression respectively.
The diagrams are plotted with the distance along the beam on the x-axis and shear force or bending moment on the y-axis.
SFD and BMD diagrams are often used in conjunction with each other to analyze and design beams.
Example: A simply supported beam with a uniformly distributed load will have a triangular SFD and a parabolic BMD.
