What are the three types of bridges?
Beam, arch, suspension
100
Name the type of bridge that is made of a flat piece laid across two or more piers.
Beam bridge
100
What is a simple machine?
Something that does work, or which makes doing work easier.
100
Name two things engineers need to think about when they design a bridge.
Where the bridge is located, what weather the place has, how much money they can spend, how many people/cars will cross it, how it should look, whether the bridge is built over land/water/etc., how long they have to build it, etc.
100
How do you know if something is technology.
If it makes life easier or solves a problem.
200
Which bridge type is used to span the shortest distances?
Beam
200
What does "span" mean?
The distance a bridge crosses without any support underneath; the distance between piers.
200
What is an inclined plane?
A slanted surface.
200
Name three materials your group used when building your bridge.
Paper, tape, popsicle sticks, string, straws, paper clips, books
200
Name two examples of technology.
Answer can include anything that makes life easier or solves a problem.
300
Which of the bridges we learned about holds the most weight?
Suspension
300
These are the parts of an arch bridge that stand at either end of the arch and hold the arch in shape.
Abutments
300
Give an example of a simple machine that is in the screw category.
Lightbulb, water bottle, lid for a jar, door lock, etc.
300
Name two steps of the engineering design process.
Ask, imagine, plan, create, improve.
300
This person's job is to fix things or make them work. Hint: The name of their job starts with "T".
Technician
400
Name two things that bridges need to be able to withstand.
Winds, waves, weather, earthquakes, etc. (name 2)
400
What is a pier?
A support for a beam bridge that helps to hold up the beam.
400
This simple machine is a wheel with a groove along its edge where a rope or cable can be placed.
A pulley
400
Describe what an engineer would think about when improving their bridge design.
Answer should describe how the engineer would improve their design to meet the requirements and be the best it can be.
400
These items are ___________ that are used to make roads: concrete, rocks, tar, and gravel.
Materials.
500
Bridges have forces which act on them. Name one force.
Gravity, weight of the car, weight of the bridge, compression force (bridge materials pushing together), tension force (bridge materials pulling apart) (Must say 1)
500
Give the definition of a civil engineer.
Engineers who work on large structures like buildings, roads, and bridges. They try to improve these structures.
500
Name four of the six simple machines we learned about.
Screw, pulley, wedge, inclined plane, wheel and axle, lever.
500
When your group's bridge was tested, it was checked for stability. What does that mean?
Stability is how stable your bridge was. That is, your bridge lay flat so that the toy car could drive smoothly across it without falling off.
500
Name two properties of a piece of wood.
How strong it is, how smooth it is, how heavy it is, etc.
