Shear force & Bending moment diagram of UDL

Question

Accepted Answer

Shear force and bending moment diagrams are graphical representations of the internal forces and moments in a beam subjected to a uniform distributed load (UDL).

A UDL is a load that is evenly distributed along the length of a beam.
To draw the shear force diagram, start from one end of the beam and calculate the shear force at different points along the beam by summing up the vertical forces.
The bending moment diagram is obtained by integrating the shear force diagram.
The shear force diagram shows the variation of shear force along the length of the beam, while the bending moment diagram shows the variation of bending moment.
The shear force is positive when it causes a clockwise rotation and negative when it causes a counterclockwise rotation.
The bending moment is positive when it causes sagging (concave upwards) and negative when it causes hogging (concave downwards).
