The amount of force (i.e., foot-pounds) required to initiate a change of direction in a straight length of material about the center of curvature.

The tendency of an applied load of series of loads acting perpendicularly to a structural member to cause bending in the member. Also, it is the ability of that member to resist the applied member.

The product of force and distance from point of support to point where force is applied causing bending or distortion.

The condition in the analysis of the internal stresses across the cross section of a member when it is subjected to forces which cause it to bend.

The Bending moment M is responsible for bending thin bodies. It induces internal forces in an element that are distributed over the component's cross-section and length.A bending moment occurs, f [..]

A system of internal forces whose resultant is a moment. This term is most commonly used to refer to internal forces in beams.

The algebraic sum of the couples or the moments of the external forces, or both, to the left or right of any section on a member subjected to bending by couples or transverse forces, or both.

The bending force in, for example, a beam. The units of bending moment are those of force x distance, for example, kiloNewton-metres.
