Bridge Facts 2
100
A simple type of bridge composed of horizontal beams supported by vertical posts. These bridges span LESS than 250 feet and are found more on local roads
What is beam
100
the outermost end supports on a bridge, which carry the load from the deck
What is abutment
100
the solid rock layer beneath sand or silt
What is bedrock
100
a stretching or pulling force
What is tension
100
a mixture of water, sand, small stones, and a gray powder called cement
What is concrete
200
A curved bridge that converts the downward force of its own weight and any weight pressing down on top into an outward force along its sides and base. This bridge has great natural strength
What is arch bridge
200
a rigid, usually horizontal, structural element
What is beam
200
any action that tends to maintain or alter the position of a structure
What is force
200
to bend under compression
What is buckle
200
the cables ride freely across the towers, transmitting the load to the anchorages at either end.
What is suspension bridge
300
Cable-Stayed Bridge - a bridge in which the roadway deck is suspended from cables anchored to one or more towers
What is cable-stayed bridge
300

a bridge or channel for conveying water, usually over long distances

What is aqueduct

300
To curve; one side squeezes together in compression, and the other side stretches apart in tension
What is bend
300
a structural element formed from steel wire bound in strands; the suspending element in a bridge
What is cable
300
an engineer who plans, designs, and supervises the construction of facilities essential to modern life
What is civil engineer
400
originally made from rope and wood Today, the cables are made of thousands of individual steel wires bound tightly together.
What is suspension pridge
400
a vertical, structural element, strong in compression
What is column
400

a pressing force that squeezes a material together

What is compression?

400
characteristic of a material that fails without warning; this type of materials do not stretch or shorten before failing
What is brittle
400
the cables are attached to the towers, which alone bear the load
What is cable-stayed bridge
500
a projecting structure supported only at one end, like a shelf bracket or a diving board
What is cantilever
500
a secure fixing, usually made of reinforced concrete to which the cables are fastened
What is anchorage
500

If this is removed an arch bridge will collapse.


What is keystone?

500

ability to resist deformation when subjected to a load

What is rigid

500
A vibration of large amplitude An object free to vibrate tends to do so at a specific rate called the object's natural, or resonant, frequency.
What is resonance
