A tool for learning. Linear elastic Euler–Bernoulli bending with constant E and I. Supports prevent vertical movement; fixed supports also prevent rotation. Pinned and roller supports have the same vertical restraint in this bending model. Axial deformation, shear deformation, self-weight, settlements and internal hinges are not included. Deflection uses the uncracked I you enter. Educational results require independent checking before design use.
