    • BRIDGES ∑ F = 0Sum of Forces equal zeroConceptual Physics Lab acloutier 2011 copyright
      Suspension, beam, truss & arch
    • Suspension - bridge having roadways suspended from cables that are anchored at either end and usually supported at intervals by towers(Milau Viaduct tallest bridge in world built 2004)
    • Singapore unique double helix design completed in 2010
    • London Bridge is not falling down Over the River Thames ~ 1825
    • Sao Paulo “X” Bridge
    • Beam Bridges
    • Chesapeake Bay Beam span bridge
    • Truss uses triangles Forces = compression & tensionGolden Gate
    • Styles of bridges to consider
    • Arch Bridge thank the Roman’s for this intelligent design
    • Roman Arch Force Vectors
    • RUBRIC:1. Draw a design off the top of your head. Make a plan/ pick a partner or chose to work alone2. Materials are plastic straws, limited glue and paper clips3. Tools are scissors, a glue gun with only two glue sticks4. Illustrate the completed bridge showing force/ tension /vectors gravity, weight N (newtons), and where ∑F=0 is the sum5. Do the physics vector and include the magnitude and distance for one specific section of the bridge.(Use graph paper if you like)6. Include a top and side view of the bridge7. Three days 90 minute effort each, any additional materials you will need to supply*Document process at the end of each of the three days
    • The End
