Details of Shear Force Diagram and Bending Moment Diagram:
Shear force diagram (SFD) and bending moment diagram (BMD) are graphical representations of the variation of shear force and bending moment along the length of a beam. These diagrams are important tools used in the design and analysis of beams and help to identify the maximum values of shear force and bending moment that the beam will experience.
The SFD is a graph of the shear force along the length of the beam, while the BMD is a graph of the bending moment along the length of the beam. The SFD and BMD are usually plotted on the same set of axes with the length of the beam along the x-axis and the shear force or bending moment along the y-axis.
The following are the steps involved in drawing the SFD and BMD:
Determine the reactions at the supports and draw the free body diagram of the beam.
Cut the beam at a section and consider the left or right part of the beam. Draw the forces acting on the left or right part of the beam and apply the equations of equilibrium to determine the shear force at the section.
Move to the next section and repeat the process to determine the shear force at that section. Plot the shear force on the SFD diagram with positive values indicating upward forces and negative values indicating downward forces.
Determine the bending moment at each section by integrating the shear force along the length of the beam. Plot the bending moment on the BMD diagram with positive values indicating sagging or concave upward deformation and negative values indicating hogging or concave downward deformation.
Continue the process until the entire length of the beam is covered. The resulting SFD and BMD diagrams provide a clear understanding of the internal forces and moments developed in the beam and can be used to determine the required strength and size of the beam and the type and size of the supports needed to ensure the beam remains stable and safe under the applied loads.
