bending machines for biomechanical testing|flexural strength testing machine : agencies A bending moment is a measure of the bending effect due to forces acting on a structural element. It's essentially a moment that induces rotational movement in a beam or another structure. Mathematically, the bending moment at a certain point along a beam is calculated as a product of the force and the perpendicular distance from the point to the line of action of the force.
