Analytical Framework and Theoretical Foundations
The beam bending lab at Georgia Institute of Technology is deeply rooted in classical
mechanics and material science theories. The Euler-Bernoulli beam theory, which
assumes plane sections remain plane and perpendicular to the neutral axis after bending,
forms the theoretical backbone of the experiments. Students apply the fundamental
