Simply Supported UDL Beam Formulas and Equations
 Below are the Beam Formulas and their respective SFD's and BMD's
A simply supported beam is the most simple arrangement of the structure. The beam is supported at each end, and the load is distributed along its length. A simply supported beam cannot have any translational displacements at its support points, but no restriction is placed on rotations at the supports.
