Euler–Bernoulli beam theory is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams. It covers the case for small deflections of a beam that are subjected to lateral loads only. It is thus a special case of Timoshenko beam theory.
Through participation in the lectures, recitations, and work associated with Unit M4.4, it is intended that you will be able to • .describe the aspects composing the model of a beam associated with deformations/displacements and stresses (i.e. Simple Beam Theory) and identify the associated limitations. • .apply the
Several beam theories have been developed based on various assumptions, and lead to different levels of accuracy. One of the simplest and most useful of these theories was first described by Euler and Bernoulli and is commonly called Euler-. Bernoulli beam theory. A fundamental assumption of this theory is that the

3. BEAMS: STRAIN, STRESS, DEFLECTIONS. The beam, or flexural member, is frequently encountered in structures and machines, and its elementary stress analysis constitutes one of the more interesting facets of mechanics of materials. A beam is a member subjected to loads applied transverse to the long dimension

To simplify further the discussion, assume for now that there is no rotation of the cross section around the e3 axis. Write the most general form of the cross-section in-plane displacement components:.
