Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific name?Euler–Bernoulli beam theory
2. What is the also known as?Engineer's beam theory, Classical beam theory
3. Why do engineers use this theory for bridges and buildings?Because it gives quick, accurate answers for beams that are much longer than they are thick, and it helped design famous structures like the Eiffel Tower and the original Ferris wheel.
4. How does the theory ignore shear deformation and rotatory inertia?It assumes those effects are tiny for slender beams, so the math only looks at bending, making the equations easier to solve.

Transverse Loads: Forces applied perpendicular to the longitudinal axis of a beam.
Neutral Axis: An imaginary line within a beam where the material experiences neither tension nor compression during bending.
Linear Elasticity: A material property where deformation is directly proportional to applied stress and the material returns to its original shape upon unloading.
