Euler–Bernoulli beam equation
- Beam cross-sections remain perpendicular to the beam axis after the deformation takes place.
- These relationships are derived from equilibrium of an infinitesimal portion of the beam.
- There relationships are derived from geometry of deformed infinitesimal portion of the beam.
