What are some examples of simply supported beams?

Simply supported beams are beams that rest on two supports at their ends and are free to rotate, allowing for bending under load. Common examples include a beam spanning between two columns in a building, a bridge supported at both ends, and a shelf resting on brackets. These beams experience shear and bending moments primarily at the mid-span due to applied loads. Additionally, simply supported beams are widely used in construction, such as in residential homes and industrial structures.
