# Euler–Bernoulli beam equation

From StructuralWiki

## Contents |

## Assumptions

- Beam cross-sections remain perpendicular to the beam axis after the deformation takes place.

## Internal Forces

- These relationships are derived from equilibrium of an infinitesimal portion of the beam.

## Elastic Curve

- There relationships are derived from geometry of deformed infinitesimal portion of the beam.
