Mary C. Lacity,Leslie P. WillcocksThe engineer’s theory of bending (ETB) enables the longitudinal bending stress ., to be found anywhere in the cross-section of an initially straight beam when the bending moment ., at that section is known. Let the radius of curvature ., in Fig. 5.la define the untrained longitudinal fibre OO, which will be referred to as the neutral axis (NA).
