5. Compression Tension
Basic
Concepts
Span - the distance between two bridge
supports, whether they are columns,
towers or the wall of a canyon.
Compression –
Tension -
Force -
Concrete has good compressive strength, but extremely
weak tensile strength. What about steel cables?

6. Basic
Concepts
Beam - a rigid, usually horizontal, structural element
Pier - a vertical supporting structure, such as a pillar
Cantilever - a projecting structure supported only at one end,
like a shelf bracket or a diving board
