What is Technology? The application of knowledge and the use of resources to meet human needs and solve problems.
Technology Resources Time Money Knowledge Power Material Tools People
Structural Efficiency Live Weight Structural Efficiency Dead Weight How many times its own weight can the structure support?
The weight of the load being applied to a structure. Live Weight The weight of the load being applied to a structure.
The weight of the structure itself. Dead Weight The weight of the structure itself.
Unit of Measure: A standard increment of measurement used as a comparison to other quantities.
A mathematical means of changing one unit of measurement into another. Conversion A mathematical means of changing one unit of measurement into another.
Calculate Efficiency Live Weight Dead Weight Efficiency = (Live Weight (Pounds) X 454) Grams ÷ Dead Weight (Grams)

Elements of Design Which of the above shapes are the strongest? Truss Gusset Arch Beam Column
The force on a structural member caused by pushing. Compression The force on a structural member caused by pushing.
The tendency of a structure to lean when lateral forces are applied. Racking The tendency of a structure to lean when lateral forces are applied.
Arch A curved structure that spans an opening, which evenly distributes a load to both sides.
Truss A structure of beams arranged in a triangular shape which prevents racking.
An angle brace or plate used to stiffen a corner to prevent racking. Gusset An angle brace or plate used to stiffen a corner to prevent racking.
A horizontal structural member which supports a load over a distance. Beam A horizontal structural member which supports a load over a distance.
A structural member that supports a vertical load. Column A structural member that supports a vertical load.
Stability The capability of a structure to be resistant to change; to be steady, strong and well balanced.
