Bending Moment

A bending moment in physics is an example of an internal force that is induced in a structure when loads are applied to that structure. Loading tends to cause failure in two main ways:

  • by shearing the beam across its cross-section.
  • by bending the beam to an excessive amount.

A bending moment may be defined as "the sum of moments about that section of all external forces acting to one side of that section".

Moments, at any point, are calculated by multiplying the magnitude of the external forces (loads or reactions) by the distance between the point at which moment is being determined followed by the point at which the external forces (loads or reactions) are being applied.
