WebAug 1, 2024 · CASE STUDY 5.1 STRESSES IN A STEEL CRANE HOOK BY VARIOUS METHODS. A load P is applied to the simple steel hook having a rectangular cross section, as illustrated in Fig. 5.27a. Find the tangential stresses at points A and B, using (a) the curved beam formula, (b) the flexure formula, and (c) elasticity theory. Derivation of the stress in the beam is again based on the three principles of solid mechanics and the familiar presuppositions: 1. All cross sections possess a vertical axis of symmetry lying in the plane of the centroidal axis passing through C. 2. The beam is subjected to end couples M. The bending moment vector … See more In Fig. 5.25a, it is clear that the initial length of any arbitrary fiber gh of the beam depends on the distance r from the center of curvature O. Thus, the total deformation of a beam fiber … See more Once we know the location of the neutral axis, we can obtain the equation for the stress distribution by introducing Eq. (a) into Eq. (c). Therefore, Expanding this equation, we have Here, the first integral is equivalent to A/R, as … See more Equations (5.70) and (5.71) represent two forms of the curved-beam formula.
