The distance a beam (bridge or other structure) must pass over
What is SPAN?
100
A force pushing down on any beam or structural unit that causes it to become smaller or pressed together
What is COMPRESSION?
100
The place along the center of a beam that is bending where there is no compression and no tension
What is NEUTRAL AXIS?
100
This engineer helps create dams, roads and bridges
What is CIVIL ENGINEER?
100
This is the simplest kind of bridge. It could be as basic as a single board across an opening
What is BEAM BRIDGE?
200
A simple and basic structural beam in a building or structure
What is MEMBER?
200
The weight of a structure by itself (All structures must be able to support their own weight)
What is DEAD LOAD?
200
An upward extension of an existing structure above a baseline
What is SUPER-STRUCTURE?
200
This engineer designs circuits and micro-processing chips for computers and cell phones
What is ELECTRICAL?
200
An example of this type of bridge would be an aquaduct
What is ARCH BRIDGE?
300
A flat piece of material used to strengthen joints (where members or beams connect in a truss)
What is GUSSET?
300
The weight of whatever is placed upon a structure
What is LIVE LOAD
300
A structure forming a foundation or framework for a building or other construction
What is SUB-STRUCTURE?
300
This engineer creates helicopters, airplanes and other flying machines
What is AERONAUTICAL?
300
The bridge in Corning over by Wegmans is this type of bridge (on Bridge St) It uses triangles for superior strength
What is TRUSS BRIDGE?
400
The height or vertical thickness of a beam or truss
What is DEPTH?
400
A force pulling on any beam or structural unit that causes it to become longer or stretched
What is TENSION?
400
This is the strongest shape and explain why
What is TRIANGLE & SIDES ARE UNDER COMPRESSION WHILE BASE IS UNDER TENSION
400
This engineer designs and changes cells to give living organisms new traits
What is GENETIC OR BIOLOGICAL?
400
This bridge has tall towers with cables connecting the towers together along with vertical cables attached to the main deck surface
What is SUSPENSION BRIDGE?
500
A structure that is made of multiple members or beams connected using triangular shapes to provide a great amount of strength and depth with a minimum amount of material
What is TRUSS?
500
A force acting across any beam or structural unit that tends to cause two parts of the same body to slide relative to each other
What is SHEAR?
500
Name three things that need to be done to keep bridges safe over time
What are INSPECT, NEW DIAGNOSTIC EQUIPMENT, MAINTENANCE, ADVANCED DESIGNS & MATERIALS
500
This engineer designs new materials and looks for ways to provide desirable properties
What is CHEMICAL?
500
The process in which a beam is made "taller" by using triangles. This makes a stronger beam without a lot of additional weight. It splits along the neutral axis.
What is CHANGING/CONVERTING A BEAM BRIDGE INTO A TRUSS BRIDGE
