Suspension Bridges Aesthetic, light, and strong, suspension bridges can span distances from 2,000 to 7,000 feet, far longer than any other kind of bridge.

Types of Bridges The five bridge types are 1.arch, 2. beam, 3. cable-stayed, 4. suspension, 5. and truss. Other variations include cantilever and moveable.

Engineers as Artists Design Construct Problem Solving Develop technological Solutions Base on these characteristics today’s engineer not only uses math, but uses fine arts to broaden engineering perspectives.

Types of Bridge Designs The types of bridges you will need to research for this assignment are: Truss Beam Arch Cantilever Suspension Cable Suspension

Brain Challenge Roman bridges were built with what material? Early Asian bridges used which bridge design? Incan civilizations of South America used a simple type of suspension bridge called ___________?

Brain Challenge Answers Roman bridges were built with what material? stone Early Asian bridges used which bridge design? cantilever Incan civilizations of South America used a simple type of suspension bridge called ___________? rope bridges

Truss Beam A Beam is the easiest of the designs to build, it is also the least expensive . Beam bridges are used for shorter distances. A truss bridge is inexpensive to construct because it uses materials efficiently. Early truss bridges in the US were built using wood.

Arch Cantilever An arch bridge is very strong and can last for centuries. These bridges are labor intensive, which means it takes many people working very hard to complete a bridge. The Forth Bridge is a cantilever railway bridge in Scotland. It is constructed from steel.

Suspension Cable Stayed A cable-stayed bridge requires less labor and materials. They can cover long spans, the Sunshine Skyway Bridge is a well known Cable Stayed bridge in the central Florida area. A suspension bridge is better for long spans. The longest suspension bridge is located in Japan.

Design Concerns As an Engineer using artistic strategies focus on: The physical principles of your bridge. Both Positive and Negative Textured Spaces need to complement each other. Keeping your design project on budget.
