What is share force and bending moment diagram ?

Question

Accepted Answer

Share force and bending moment diagrams are graphical representations of internal forces and moments in a structural element.

Share force diagram shows the distribution of shear forces along the length of a beam.
Bending moment diagram shows the distribution of bending moments along the length of a beam.
These diagrams are essential for analyzing the behavior of structural elements under different loading conditions.
They help engineers determine the maximum stresses and deflections in a structure.
Example: In a simply supported beam with a point load at the center, the shear force diagram will show a constant positive value on one side and a constant negative value on the other side.
Example: The bending moment diagram for the same beam will be a parabolic curve with maximum value at the center.
