WebBeams are traditionally descriptions of building or civil engineering structural elements, where the beams are horizontal and carry vertical loads. However, any structure may … WebThe beam distributes the load back to the support where it is forced against a moment and shear stress. Cantilever beams allow the creation of a bay window, balconies, and some bridges. Fig. 3: Cantilever beam 4. Continuous Beam A continuous beam has more than two supports distributed along its entire length. Fig. 4: Continuous beam
