Study Notes
Bending Moment in Structural Engineering
- The bending moment refers to the rotational force that causes a beam to bend or deform, resulting from the application of external loads.
Effect of Positive Bending Moment on a Beam
- A positive bending moment causes the beam to sag or curve downward, resulting in compression on the top surface and tension on the bottom surface.
Bending Moment at a Fixed End of a Simply Supported Beam
- At a fixed end of a simply supported beam under a uniform load, the bending moment is zero, as the beam is restrained from rotation.
Effect of Increasing Span on Bending Moment
- Increasing the span of a beam increases the bending moment, as the external load is applied over a longer distance, resulting in a greater rotational force.
