Draw shear force and bending moment diagrams

Question

Accepted Answer

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

Shear force diagram shows the variation of shear force along the length of the element.
Bending moment diagram shows the variation of bending moment along the length of the element.
Shear force and bending moment diagrams are commonly used in structural analysis and design.
These diagrams help engineers understand the internal forces and moments acting on a structure.
They are useful for determining the maximum bending moment and shear force in a structural element.
Shear force is represented by a line graph, while bending moment is represented by a curve graph.
Shear force changes sign at points where the applied loads change direction.
Bending moment is zero at points where the shear force is maximum or minimum.
The diagrams are typically drawn by considering the applied loads, support conditions, and geometry of the structure.
