Shear force diagram and bending moment diagram for combination of different loads

Question

Accepted Answer

Shear force and bending moment diagrams show the variation of forces and moments along a beam subjected to different loads.

Shear force diagram represents the variation of shear force along the length of the beam.
Bending moment diagram represents the variation of bending moment along the length of the beam.
Different loads such as point loads, distributed loads, and moments can be combined to create a composite load on the beam.
To draw the shear force diagram, calculate the reactions at supports and then plot the changes in shear force at different points along the beam.
To draw the bending moment diagram, calculate the reactions at supports and then plot the changes in bending moment at different points along the beam.
The diagrams help in understanding the internal forces and moments acting on the beam, which are crucial for designing and analyzing structures.

Accepted Answer

Shear force refers to the force that acts parallel to the cross-section of a structural element, while bending moment is the moment that occurs when an external force is applied to the element causing it to bend.
