Page 87 - moment of a force" is necessary. Since the tendency to bending, to which a given beam is subject at any point, depends upon the moments of the stresses about that point, it is obvious that the relative strengths of beams may be measured in terms of moments. The bending moment at any given section is the algebraic sum of all the external forces acting on one side of the section. Since it is at the point where the greatest bending moment occurs that the beam is subjected to the greatest stress, it...
