What is a structural system utilizing the cable as the principle means of support?
CABLE STRUCTURE
What are flexible structural members, such as a wire rope or metal chain, having high tensile strength, but offering no resistance to compression or bending

FUNICULAR SHAPE
What is the shape assumed by a freely deforming cable in direct response to a set of concentrated loads?
FUNICULAR POLYGON
What is the shape assumed by a freely deforming cable indirect response to a uniformly distributed load?
FUNICULAR CURVE
What is the curve assumed by a perfectly flexible uniform cable suspended freely from two points not in the same vertical line?
CATENARY
What is a structure shape to carry or support a given loading by either axial tension or compression?
FUNICULAR STRUCTURE
What is a lens-shaped structure having the outward thrust of an arch balanced by the inward pulse of a cable, resulting in no net lateral forces at the supports?
LENTICULAR STRUCTURE
What is a structure of cable suspended and pre-stressed between compression members to directly support applied loads?
SUSPENSION STRUCTURE
What bridge has a deck suspended from cables raised on towers and securely anchored to abutments at the ends?
SUSPENSION BRIDGE
The first two is suspension structure utilizing a parallel series of cables to support surface forming beams or plates. This structure is susceptible to flutter induced by the aerodynamic effects of wind. This liability can be reduced by increasing the dead load on the structure or anchoring the primary cables to the ground with transverse guy cables
SINGLE-CURVATURE STRUCTURE
What is a cable for absorbing the horizontal component of thrust in a suspension or cable-stayed structure and transferring the force to a ground foundation?
GUY CABLE
What is a vertical or inclined compression member in a suspension or cable stayed structure supporting the sum of the vertical force components in the primary and guide cables; inclining this member enables it to pick up some of the horizontal cable thrust and reduces the force in the guy cables?
MAST
What is a suspension structure having upper and lower sets of cables of different curvatures pretensioned by ties or compression struts to make the system more rigid and resistant to flutter?
DOUBLE-CABLE STRUCTURE
Reference to one of the pretension cables directly supporting the load on a suspension structure
PRIMARY CABLE
Refers to one of the pretention cables used for stabilizing a suspension structure against flutter, usually having a curvature opposite to that of the primary cables
SECONDARY CABLE
What is a cable for anchoring a set of secondary cables in a suspension structure?
BOUNDARY CABLE
What is a suspension structure composed of a field of crossed cables of different and often reverse curvatures. Each set of cables has a different natural period of vibration, thus forming a self-dampening system that is more resistant to flutter?.
DOUBLE-CURVATURE STRUCTURE
What structure has vertical or inclined mass from which cables extend to support horizontally spanning members arranged in a parallel or radial pattern?
CABLE-STAYED STRUCTURE
what is the overhead interior surface of the lining of a room, often concealing the underside of the floor or roof above?
CEILING
What is the underside of a floor showing the supporting beams and finished to form a ceiling?

What is the secondary member of the grid supporting a suspended ceiling system, usually a sheet-metal tree carried by the main runners?
CROSS TEE
What is a thin metal strip inserted into the edges of two acoustical tiles to make a butt joint between them?
