Part 2: True—False
Directions: Read each statement below carefully. Place a T on the line if you
think a statement it TRUE. Place an F on the line if you think the statement is
FALSE. If you have questions, raise your hand and ask your teacher. (2 points
each, for a total of 20 points).
The two main forces that act on a bridge at any given time are compression
and repression.
_____6.
_____7. Usually, a poor foundation can be easily fixed.
_____8. Sometimes, foundations must go deeper into the ground than a structure is
tall.
_____9. The three types of foundations are shallow, deep, and semi-deep.
_____10. One challenge to building in a narrow mountain canyon is that sometimes
there are no flat or straight open areas for road surfaces.
_____11. Engineers are continually refining the materials used to make the members
(beams, piers, columns, girders) of a bridge to construct safe and dependable bridges.
_____12. Reinforced pressure is the weight or force bearing down on the soil from the
bottom of the foundation
_____13. Settlement is the vertical downward movement of the foundation.
_____14. Foundations are often the most overlooked part of a bridge or any building
_____15. Compression is the force responsible for most bridge failures.

2.
If you were an engineer, how would you go about designing a bridge to make sure it was safe?
3.
Engineers must consider many things when designing the foundation for a bridge or structure.
What are some of those things?

4. What happens to the size of a foundation as a building or bridge gets bigger? The foundation
must increase in size. Why?
5. What are reasons why people want roadways like those in Glenwood Canyon?
6. Why does it matter to us that engineers are careful to balance the cost of a bridge with their
design decisions?
7. Explain at least 3 factors influence bridge cost.
8. What factors do you think are most important in the cost of a bridge? Be sure to back up your
opinion with examples from our unit. You can use famous bridge examples if you wish.
