Short Answer

What is the difference between a solid structure, frame structure, and shell structure?




Using houses as an example, explain why houses have a variety of different roofs since they all do the
same thing.




With your knowledge of center of gravity explain what happens when the center of gravity of a building
or any other structure is too much to one side.




What is the difference between internal and external forces?




What effects do magnitude, direction and location have on a structure? Be sure to explain each.
What is the difference between compression, tension, and shear forces?
