Presentation Transcript

  1. BINGO Unit 4 Review!

  2. Has a thin, carefully shaped outer layer (ex. Balloon)

  3. Shell Structure

  4. When two identical materials are fused together using heat

  5. Welding

  6. A push or pull, or anything that causes a change in motion of an object

  7. Force

  8. The force of gravity exerted on an object. It changes if you are on the moon.

  9. Force

  10. A type of structure in which a skeleton of materials supports the weight of the other parts. Ex. A chair

  11. Frame Structure

  12. Kilogram • The primary standard for mass- the unit used to measure mass. How many newtons does 1 kg weight on Earth?

  13. A process that uses a different material to join two materials together by melting?

  14. Soldering

  15. Examples of these are nails, screws, and rivets

  16. Fasteners

  17. The weight of a structure upon itself- a type of external force

  18. Dead load

  19. The unit that force is measured in.

  20. Newton

  21. When a layer of material is pressed or glued onto other layers

  22. Lamination

  23. This ensures that a structure has extra strength to support more load than normal

  24. Margin of Safety

  25. An object with a definite size and shape, which fulfills a specific purpose or function. The parts have a specific arrangement that stays the same

  26. Structure

  27. An example of this is the motion of a bicycle wheel- the reason you can ride with no hands sometimes!

  28. Spin Stabilization

  29. When two parts are pressed in opposite directions at the same time. Ex avalanche

  30. Shear

  31. This internal force crushes a material by squeezing it together

  32. Compression

  33. The amount of matter in a substance; often measured with a balance

  34. Mass

  35. Made of two or more different materials

  36. Composite

  37. The point at which all of the gravitational force of an object may be considered to act. It needs to be balanced in a stable structure

  38. Centre of gravity

  39. A force that pulls a material apart

  40. Tension

  41. A structure that is made by piling up materials. Example: pyramid

  42. Mass Structure

  43. A force that twists the ends of a material

  44. Torsion

  45. There are two types of these; solvent-based, which harden as they dry out, and thermosetting, which harden as they cool

  46. Adhesives

  47. A force on a structure that is not part of the structure itself. Ex. Wind, weight of people, collision

  48. Live load
