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. Force

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

8. Force

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

10. Frame Structure

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

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

13. Soldering

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

15. Fasteners

17. The unit that force is measured in.

18. Newton

19. Lamination

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

21. Margin of Safety

22. 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

23. Structure

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

25. Spin Stabilization

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

27. Shear

28. Compression

29. Mass

30. Made of two or more different materials

31. Composite

32. 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

33. Centre of gravity

34. A force that pulls a material apart

35. Tension

36. Mass Structure

37. A force that twists the ends of a material

38. Torsion

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