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 Curved structures known for?Mastery of the voussoir arch and concrete dome
2. What is the primary force resistance?Compression along the curved axis
3. What is the ideal curve for hanging load?Catenary curve (inverted for arch)
4. What makes curved buildings stronger than straight ones?Curved shapes spread forces along the curve, using compression instead of bending. This lets them hold big loads with less material, making them strong and lighter.
5. Why do arches use compression to hold up weight?In an arch, the weight pushes down and the shape turns that force into straight lines along the curve. Those straight lines are compression, which stones and concrete are very good at handling.

Voussoir: A wedge-shaped stone used in constructing an arch or vault.
Catenary: The curve formed by a flexible chain or cable hanging freely between two points.
Shell Structure: A thin, curved surface that derives its strength from its shape.
