  3. Hello everybody. Our company has been given the contract to repair the rope bridge in Kotyaevka village. The villagers have come to us because their existing bridge has collapsed and they need it repairing or replacing quickly. Engage Rope BridgeBroken bridge

  4. Engage Rope BridgeBroken bridge This bridge is seriously damaged! It will need replacing. But is a rope bridge the best sort of crossing for the river here? 4

  5. Maybe we should just build a pier across the river out of stones and earth like this one in China? Engage Rope BridgeBroken bridge

  6. This is flat and uses bamboo poles for the railings at the sides. Engage Rope BridgeBroken bridge 6

  7. Or steel wires and wood like this one? Engage Rope BridgeBroken bridge

  8. Engage Rope BridgeBroken bridge And how about a stone one with lots of lights on it - like this one in Amsterdam?

  9. Engage Rope BridgeBroken bridge And how about this way to get across the river? 9

  10. Engage Rope BridgeBroken bridge Or maybe people should just use boats?

  11. Engage • Please decide what sort of bridge or river crossing would be best for our village. Remember to think about: • what it will need to carry? • how long it will take to build? • how far it has to reach? • how much it will cost? • how easy it will be to repair if some parts fail? • Please work in teams to come up with the best sort of crossing for the river - and be ready to give me your reasons!

  12. Explore What forces act on the bridge ? What experiment could we do to tell us about the forces acting on the bridge? What is holding the bridge up? Rope BridgeBroken bridge How could the forces have damaged the bridge? Is it gravity? That has something to do with the weight? SS1

  13. How could the bridge have been damaged ? Here are two pictures of bridges that have failed in different ways. What caused them to break? How could we make a stronger bridge? Explain Rope BridgeBroken bridge

  14. Elaborate You’ve probably noticed some bridges are flat but some bend downwards and others bend up. Does the shape make any difference to the strength of the bridge? Rope BridgeBroken bridge
