This is us setting up a "suspension bridge" of our own. We got this idea from a website called NOVA Online. So go check it out at PBS.org. It's a demonstration to show the forces of tension and compression. When we set up the towers we pushed on the "roadbed" to simulate a car driving across, and the book towers collapsed. When we added anchorages to hold the cables, they gave the towers tension to counteract the compression. With the anchorages, the book towers didn't collapse |

The anchorage extends the cables to prevent the two towers from bending. There are three parts (blocks) of the anchorage. One is the base block, the next is the anchor block, and the last is the weight block. Eye bars are attached to the beams in the concrete. The strands from the cable are attached to the eye bars. |
|
Towers are used to hold up the cables. Towers need to be close together and tall enough so the bridge will have enough support. |
|
| The main cables are made up of many strands of wire which
are brought to the building site on reels. The wheel called the
"traveler" carries the wires up to the towers and down to the
anchorage where they get attached
to the eye bar.
Suspender ropes are attached to the main cable, which are eventually attached to the roadway. |
|
The roadbed hangs from the cables and is the last part built on the bridge. The roadbed is the part that cars drive on to get to the other side. |
