Calculate beam deflection online: this is a collection of tools for calculating the deflection of beams in various scenarios, such as beams on two columns with line load, cantilever beams with fixed restraint, statically indeterminate beams (beam on 3 supports), etc. based on the Bernoulli beam bending. If you are looking for section modulus calculations, try the category Tools/Sections. In each beam calculator you can choose between metric and imperial units for calculation.
With this online calculator for beam bending, you can determine the deformation, support reactions, bending moments and bending stresses for a statically overdetermined, both sides clamped beam under line load.
