3. What is a bridge and how does it help us?Bridges are structures that let us cross rivers, valleys, and roads, connecting places and people. They carry weight from the deck to foundations using forces like tension and compression.
4. Why do different types of bridges use different designs?Each type, like beam, arch, truss, suspension, or cable‑stayed, uses a special way to handle forces so the bridge stays strong and safe.

Tension: A pulling force that tends to stretch or elongate a material.
Compression: A pushing force that tends to shorten or squeeze a material.
Abutment: The structure at either end of a bridge that supports the bridge deck and transfers load to the ground.
