Transcript of "Lippy"

  1. 1. Structures and bridges By hospital 991
  2. 2. The arch bridge is used for heavy weight objects. When a heavy object applies on the bridge all the weight pushes to the supporters on the left and right. Arch bridge
  3. 3. Beam bridge A beam bridge has two supporters on each end A longer beam bridge may be supported by additional piers[vertical supports]
  4. 4. Truss bridges A truss bridge is light weight but strong and made of trusses[triangle – shaped frames] along its sides.
  5. 5. Suspension bridge The to end s of the bridge may be hung by trees. A modern suspension bridge has tall towers on either end that support the main cables holding up the bridge. The main cables are anchored to concrete to hold up the bridge.
  6. 6. Solid structure A solid structure is formed from a solid piece or a solid combination of pieces of strong material. A solid is not halo. A sold structure is more stronger than a frame and a shell structure. A solid has little space or none at all.
  7. 7. Frame structure A frame structure is made up of a rigid arrangement of parts or structural components, fastened together. Example is an a skeleton.
  8. 8. Shell structure A shell structure has a solid outer surface, witch may be rounded or a flat shape.
  9. 9. shear Shear is a force that acts to push parts that are contact with each other in opposite directions. Structures with parts that must resist shear in clude doors, airplanes, and scissors.
  10. 10. Tension Tension is a force that acts to stretch and pull apart something
  11. 11. Compression Compression is a force that acts to squeeze an object or push parts within an object together.
  12. 12. Compression, tension and shear Internal forces can be classified by the direction in witch they act within an objects.
