Shear & Moment

When loads act on a beam, they create two critical internal effects that engineers must calculate and visualize: shear force (V) and bending moment (M).

Shear Force (V)
The internal vertical force that tries to slide one section of the beam past the other (like scissors cutting paper). We plot this on the Shear Force Diagram (SFD).
Bending Moment (M)
The internal twisting effect that bends the beam, creating tension on one face and compression on the other. We plot this on the Bending Moment Diagram (BMD).

Assumptions

Static Analysis: The system is at rest with no changing forces or vibrations.

No Self-Weight: The beam's own weight is negligible compared to the applied loads.
