Bear Mountain Bridge
Slab stone bridge
Port Mann Bridge
A _________________ bridge uses shapes such as triangles and trapezoids to give it strength.
A ___________________ bridge has a curved bottom and is usually supported at the ends. Covers small distances usually over a small stream or uneven surface.
A _______________ bridge is meant to cover great distances. Usually very expensive to make but are very appealing. (Example: golden gate bridge)
A _____________ bridge uses cables to distribute the tension load to usually a central or pair of vertical beams.
A _________________ bridge is a bridge built using structures that project horizontally into space, supported on only one end.
__________________ bridges, also known as stringer bridges, are the simplest structural forms for bridge spans supported by an abutment or pier at each end.
A force caused by the state of being stretched.
Force caused by the act of being squeezed together.
The weight of the bridge that must be supported by the structure of the bridge.
The steps that engineers use to design something to solve a problem
The outermost end supports on a bridge, which carry the load from the deck
The distance a bridge extends between two supports.
The vertical structure in a suspension bridge or cable staryed bridge from which cables are hung
A strain produced when material is twisted
A structure built over an obstacle, such as a river or a road.
Supported roadway on a bridge.
A structural support; to strengthen and stiffen a structure to resist loads.
An engineer who plans, designs, and supervises the construction of facilities essential to modern life. (examples: bridges, buildings, roads, etc..)
A mixture of water, sand, small stones, and a gray powder called cement.
