structures/Bridges

TermDefinition
compression suspension bridge dissipate The force of compression pushes down on the suspension bridge's deck, but because it is a suspended roadway, the cables transfer the compression to the towers, which dissipate the compression directly into the earth where they are firmly entrenched.
buckle bend and give way under pressure or strain.
tension mental or emotional strain.
stable (of an object or structure) not likely to give way or overturn; firmly fixed.
torsion the action of twisting or the state of being twisted, especially of one end of an object relative to the other.
cantilever is a rigid structural element, such as a beam or a plate, anchored at one end to a support from which it protrudes; this connection could also be perpendicular to a flat, vertical surface such as a wall.
buckling is a mathematical instability that leads to a failure mode. When a structure is subjected to compression stress, buckling may occur. Buckling is characterized by a sudden sideways deflection of a structural member.
cable an insulated wire or wires having a protective casing and used for transmitting electricity or telecommunication signals.
Abutment a structure built to support the lateral pressure of an arch or span, e.g. at the ends of a bridge.
beam a long, sturdy piece of squared timber or metal spanning an opening or part of a building, usually to support the roof or floor above.
snapping the action of breaking suddenly and completely, typically with a sharp cracking sound.
joint a point at which parts of an artificial structure are joined.
transfer move from one place to another.
pier a platform supported on pillars or girders leading out from the shore into a body of water, used as a landing stage for boats.
truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object"
torsion the action of twisting or the state of being twisted, especially of one end of an object relative to the other.
arch bridge is a bridge with abutments at each end shaped as a curved arch
Force can cause an object with mass to change its velocity, i.e., to accelerate
beam bridge are the simplest structural forms for bridge spans supported by an abutment or pier at each end.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
