Introduction to Bridges Railroad Signals Defining Geotechnical Engineering Glider Airplanes Green Vehicles
100
What is the reason for why we build bridges?
These are built to go over obstacles.
100
What are railroad signals?
These are used to prevent train collisions.
100
What is geotechnical engineering?
This is the study of the earth to make sure it is suitable for construction.
100
What is lift?
This is the force that causes upward movement for a plane and acts opposite of gravity.
100
What is a bicycle?
This is the "greenest" form of transportation.
200
What is the beam bridge?
This is the simplest type of bridge.
200
What is 1 mile?
This is the distance it takes for a freight train to stop when traveling 55 mph - 1, 3 or 5 miles.
200
What are geotechnical engineers?
These persons are needed whenever there is construction happening.
200
What is drag?
This is the force that acts opposite of thrust.
200
What is a(n) (e.g., solar, electric, hydrogen, biodiesel) vehicle?
This is an example of an alternative fuel vehicle.
300
What is the triangle?
This is the geometric shape that makes trusses so strong.
300
What is "safe" or "dangerous?"
Ball signals that are raised or lowered communicate this to train engineers.
300
What is the construction site?
Geotechnical engineers go here to get samples of environmental materials to test.
300
Who are the Wright brothers?
These are the people that invented the first airplane.
300
What are (e.g., bike lanes, signals, crosswalks)?
These are 2 ways to make biking on roads safer.
400
What is the aqueduct?
This system was used to carry water and was built by the Romans.
400
What are blocks?
Tracks are divided into these types of sections to space trains far enough apart so they will not collide (hint: the shape of a Lego).
400
What is a laboratory?
Geotechnical engineers go here to test the samples of environmental materials.
400
What is Kitty Hawk?
This is where the first manned flight took place.
400
What is bike share?
This is when a person rents a bike, rides it and returns it to a designated bike rack.
500
What are (e.g., Truss, Beam, Cantilever, Arch and Suspension)?
These are examples of 3 types of bridges that we learned in RRRC this year.
500
What is an electric circuit?
The activity you completed for the Railroad Signals presentation.
500
What is the Leaning Tower of Pisa.
The river near this famous Italian structure, rose and caused the ground around it to get soft and the structure to lean.
500
What is the Bernouilli's Principle?
This is the principle that creates lift.
500
What are (e.g., environmentally clean, healthy for the rider, reduces roadway traffic, cheap - no gas)?
These are 2 benefits for riding a bicycle instead of driving a car.
