Bending Moment
Bending Moment is a core engineering term. Definition, usage notes, and a practical example.
Definition
Bending moment is the force effect that causes bending at a section.
Why it matters
It is a key input for stress in beams, shafts, and plates.
How it is used
In a design check, first define the relevant load, dimension, material, or flow condition. Then interpret this term by its role in the formula and compare it with limits.
Moment = Force x distance
Example
A simply supported beam with center load usually has maximum moment at midspan.
