What is a bridge?
A structure that provides a path over water, busy roads, and more.
Beam bridges are perfect for cars. True or false?
a) True
b) False
b) False. Beam bridges aren't strong enough to hold cars
Which bridge was invented first? Was it the beam, the truss or the suspension bridge?
It was the beam bridge!
A bridge that is just a single beam is called a:
a) Beam bridge
b) Plank bridge
c) Bar Bridge
d) Suspension bridge
a) Beam bridge
The Golden Gate Bridge is a Suspension Bridge. True or False?
a) True
b) False
a) True
Why are beam bridges not that strong?
There aren't as many pillars or structures involved to hold the weight of cars
A bridge that uses triangle shapes to evenly hold weight is called:
a) Beam Bridge
b) Truss Bridge
c) Suspension Bridge
d) Plank Bridge
b) Truss Bridge
All bridges are built with triangle shapes to hold the weight of people and cars. True or False?
a) True
b) False
b) False. Beam bridges and suspension bridges don't use triangle shapes
How do suspension bridges hold the weight of cars?
The cables help transfer weight evenly to multiple bridge pillars
A bridge that is hangs from cables is called a:
a) Beam Bridge
b) Truss Bridge
c) Suspension Bridge
d) Plank Bridge
c) Suspension Bridge
All bridges hang from cables to carry the weight of cars. True or false?
a) True
b) False
b) False. Only suspension bridges hang from cables
How do the triangle shapes in truss bridges help hold the weight of cars?
The cars' weight hits the point of the triangle and then the weight is distributed evenly to all sides of the triangle
