Peter Seddon,Sara Cullen,Leslie P. WillcocksA system of forces . etc, acting through a common point O, in the same plane (Figure 2.la), is in equilibrium when the algebraic sum of its force components ., in the . and . directions, is zero. It follows from this that the polygon of force vectors (Fig. 2.1b) will close.

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).

Information Systems and Qualitative ResearchThe flexure equation will enable us to calculate the slope and deflection of an initially straight beam due to bending. Consider a portion of a beam’s neutral axis AB under the positive hogging moment . shown in Fig. 6.1a.
