the value of the stress and strainat each point in the bent beam proceed as follows: Consider the portion of the beam which lies between the radiiR and R, Fig. 88. This portion is shown to a larger scale inFig. 92. Let R be the radius of curvature of the median line pp,then the length of pp is… … Fig. 91. y being considered negative for filaments below the median line.The radius of curvature of this filament is R + y and its length is(R + y)9. Therefore, the increase of length of this filament dueto the banding of the beam is yd, and, expressing this increaseof length as a fraction of the…
