|supports at the end of an arch bridge that carry the load and keep the form spreading out.
|vertical supports of an arch bridge used to distribute the weight of the roadway to the arch below.
|securing devices that are embedded in the solid rock or massive concrete blocks that spread cables over a large area to evenly distribute the load and prevent the cables from breaking free.
|the distance between two bridge supports
|a force that acts to compress or shorten the thing it is acting on .
|a force that acts to expand or legthen the things it is acting on.
|what happens when the force of compression overcomes a object ability to handle compression.
|what happen when tension overcomes an objects ability to handle tension.
|to spread force over the greater area so that no one spot has bear the brunt of the concentrated force.
|to move force from an area of weakness to an area of strength .
|supporting lattice work added to create very tall beams that add-rigidity to an existing beam greatly in creasing its ability to dissipate the compression and tension .
|a rotational or twisting force
|deck stiffening trusses
|a supporting truss system beneath the bridge deck
|a fatal force to a bridge that is a vibration caused by an extended force that is in harmony with the natural vibration of the original thing. resonance vibrations travel through a bridge in waves.
|a technique used to interrupt the resonant waves.
