1.5.2. Cables and arches

Try these first

1. 1.

   What force do cables primarily use to support loads?

   Hint

   Think about how a rope works when you pull on it.

2. 2.

   What is the primary force acting on an arch?

   Hint

   Consider how a bridge arch holds up its weight.

3. 3.

   What do cables primarily bear loads through?

   • Compression
   • Tension
   • Bending

   Hint

   Remember the difference between types of forces.

4. 4.

   True or False: Arches are flexible structures.

   • True
   • False

   Hint

   Think about how an arch looks.

5. 5.

   Design a bridge that incorporates both cables and arches and describe the forces acting on each element.

   Hint

   Consider how forces are directed in a bridge.

6. 6.

   Analyze a failure case of a cable-stayed bridge. Identify potential reasons for cable failure and their impact on the arch structure.

   Hint

   Think about how the integrity of one part affects others.
