What is Technology?

• The application of knowledge and the use of
  resources to meet human needs and solve problems.

3
Technology Resources

• Time
• Money
• Knowledge
• Power

• Material
• Tools
• People

4
StructuralEfficiency
Live Weight
Dead Weight

• How many times its own weight can the structure
  support?

5
LiveWeight

• The weight of the load being applied to a
  structure.

6
Dead Weight

• The weight of the structure itself.

7
Unit of Measure

• A standard increment of measurement used as a
  comparison to other quantities.

8
Conversion

• A mathematical means of changing one unit of
  measurement into another.

Technology System Model
12
Research is an essential part of any new
technology.
13
Elements of Design
Which of the above shapes are the strongest?

• Truss
• Gusset

Arch Beam
Column
14
Compression

• The force on a structural member caused by
  pushing.

15
Racking

• The tendency of a structure to lean when lateral
  forces are applied.

16
Arch

• A curved structure that spans an opening, which
  evenly distributes a
• load to both sides.

17
Truss

• A structure
• of beams arranged in a triangular shape which
  prevents racking.

18
Gusset

• An angle brace or plate used to stiffen a
  corner to prevent racking.

19
Beam

• A horizontal structural member which supports a
  load over a distance.

20
Column

• A structural member that supports a vertical load.

21
Stability

• The capability of a structure to be
  resistant to change to be steady, strong and
  well balanced.

22
Scientific Method

• Define the problem
• Develop a hypothesis
• Establish a procedure
• Perform procedure
• Collect data
• Evaluate data
• Conclusion
