To quickly assess the difficulty of the text, read a short excerpt:
PROB. 53. A beam 28 ft. Long overhangs the right-hand sup- port a distance of 7 ft. The beam carries a load of 6000 Ibs. At the extreme right end and also loads of 2000 and 3000 Ibs. Located 8 ft. , and 12 ft. From the left end. Find the reaction of the supports. ART. 19. BENDING MOMENT It is apparent that the tendency of the external forces, or loads, acting on a beam will be to cause a flexure or bending of the beam. This tendency increases with the external loads and the span of the beam. Th...e bending moment at any section of a beam is defined as the algebraic sum of the moments of all the forces acting to the left of the given section. The bending moment at the left-hand support equals zero, as there are no forces to the left of this section. The bending moment at the right- hand support equals zero in order to maintain the condition of equilibrium. Between the two reactions the bending moment will vary. The point in the beam at which the bending moment is the greatest or a " maximum " is called the dangerous section of the beam, for at this point the internal stress is also a maximum.
