A bridge made entirely of stone arches
A bridge supported by solid beams underneath the roadway
A bridge that floats on water using pontoons

List the Pro for a Beam Bridge.
Simple to build, inexpensive, most efficient over short spans
Requires complex construction methods
Best for very long spans
Very expensive to maintain
List the Con for a Beam Bridge.
Limited span, heavy boat traffic can't pass underneath, design is not very interesting
Can withstand earthquakes easily
Ideal for very long spans
Requires very little maintenance
List the Pro for a Truss Bridge.
Extremely strong, most drawbridges are truss designs
Requires frequent maintenance
Easily collapses under heavy loads
Difficult to construct over short spans
List the Con for a Truss Bridge.
Very heavy, limited span distance, hard to extend once built
Easily collapses under light loads
Requires no maintenance
Best suited for underwater construction
List the Pro for an Arch Bridge.
Wide range of materials can be used, generally considered an attractive design, very strong
Requires frequent maintenance, limited material options, weak structure
Difficult to construct, unattractive design, low durability
Only suitable for short spans, high cost, prone to collapse
List the Con for an Arch Bridge.
Relatively expensive, designs are limited to certain sites
Very easy to construct in any location
Requires no maintenance over time
Can only be made from wood
List the Pro for a Cable-Stayed Bridge.
Span medium distances, less expensive and easier to build than the modern version, considered visually appealing
Require frequent maintenance due to complex design
Are only suitable for very short spans
Are the most expensive type of bridge to construct
List the Con for a Cable-Stayed Bridge.
Typically more expensive than other types besides modern suspension, challenging to build
Easier to construct than beam bridges
Requires no maintenance
Ideal for very short spans
List the Pro for a Modern Suspension Bridge.
Spans long distance, considered visually appealing, allows large traffic to pass under easily
Requires frequent maintenance, limited to short spans
Difficult to construct over water, not visually appealing
Blocks large ships from passing underneath
List the Con for a Modern Suspension Bridge.
Very expensive and complicated to build
Requires frequent painting to prevent rust
Cannot span long distances
Not aesthetically pleasing
What is a Dead Load in the context of bridges?
The weight of any component in a structure
Temporary forces that act on a bridge
The length of the bridge
The color of the bridge
Which of the following is an example of a Live Load on a bridge?
Beams
Piers
Cars
Towers
List some possible materials that can be used in bridges.
Bricks, concrete, steel, wood, iron
Paper, plastic, rubber, glass
Wool, cotton, silk, leather
Sand, clay, straw, bamboo
When given a triangle, square, and rectangle, which is the strongest when compression is applied to the structure and why is it the strongest?
Triangles are the strongest because it is made up of the least number of sides, locking its three sides into place.
Squares are the strongest because all sides are equal and angles are right angles, making them stable under compression.
Rectangles are the strongest because their longer sides can distribute force more evenly.
All three shapes are equally strong under compression because they are all polygons.
Which type of bridge is best suited for spanning very long distances over water?
Truss Bridge
Beam Bridge
Modern Suspension Bridge
Arch Bridge
What is a primary advantage of using steel as a material in bridge construction?
It requires no maintenance
High strength and durability
It is biodegradable
It floats on water
Which of the following is considered a Dead Load on a bridge?
The weight of the bridge deck
Pedestrians crossing
Passing vehicles
Wind pressure
Which of the following best describes a Live Load on a bridge?
The weight of the bridge's cables
The force of wind acting on the bridge
The weight of vehicles and pedestrians crossing the bridge
The weight of the bridge's foundation
What type of bridge is this?
Arch
Suspension
Beam
Truss
What are the two ends of a bridge (the bank) that support its weight?
Hanger
abutment
cable
Deck
Draw an example of the side view for a Truss Bridge!
What force helps an arch bridge support its live and dead loads?
shear
tension
compression
torsion
The distance between bridge supports.
towers
span
cables
deck
Bridge B collapsed under its own weight. What cause the collapse?
the live load
the environmental load
too much traffic on the bridge
the dead load
What is tension?
a sliding force
a twisting force
a squeezing force
a pulling force
What is compression?
a sliding force
a twisting force
a squeezing force
a pulling force
A beam is
horizontal
vertical
Draw what a Modern Suspension Bridge would look like for the side.
Which force is primarily resisted by the cables in a suspension bridge?
Shear
Tension
Torsion
Compression
