A beam is simply support at the ends and is continuous over two spans. A Simply Supported Beam is any 'beam' supported at or near each end - usually with a Pin Joint at one end and a roller or similar at the other (to allow for expansion and contraction, for example, and to ensure the Reaction at that point is always vertical). Consider the case of the beam discussed earlier shown above. Knowing that the slope on the real beam is equal to the shear on conjugate beam and the deflection on real beam is equal to the moment on conjugate beam, the shear and bending moment at any point on the conjugate beam must be consistent with the slope and deflection at that point of the real beam. 4 Pure Bending of a Beam Consider the bending of a rectangular beam by a moment M0, as shown in Fig. The overhanging beam is a combination of simply supported beam and a cantilever beam.
