the outermost end supports on a bridge, which carry the load from the deck
a secure fixing, usually made of reinforced concrete to which the cables are fastened
the inverse of a funicular form; the form taken by a structure with applied downward loads such that the entire structure is in compression
a curved structure that converts the downward force of its own weight, and of any weight pressing down on top of it, into an outward force along its sides and base
a structural element that is capable of withstanding loads applied perpendicular to the element
a simple type of bridge, composed of horizontal beams supported by vertical posts
the curved shape taken by a slender element when loads are applied perpendicular to the element
to bend under compression
a support that transmits a force from a roof or wall to another supporting structure
a bridge in which the roadway deck is suspended from cables anchored to one or more towers
a projecting structure supported only at one end, like a shelf bracket or a diving board
a vertical member that supports downward loads applied parallel to the length
A force “pushing” (force that is directed toward) the member
A limitation, such as money, people, skills, or available materials
A supported roadway on a bridge
a curved roof enclosing a circular space; a three-dimensional arch
Form taken by a cable or rope under any given load
Any action that tends to maintain or alter the position of a structure
weight distribution throughout a structure; loads caused by wind, earthquakes, and gravity, for example, affect how weight is distributed throughout a structure
a preliminary model of a new product or process
a force that causes parts of a material to slide past one another in opposite directions
(n.) the distance a bridge extends between two supports; (v.) to traverse a specific distance
the measure of a structure's capacity to resist deformation
Strain is the deformation of a material from stress. It is simply a ratio of the change in length to the original length.
Strain is a unitless quantity and is represented by the letter epsilon (ε). Strain formula = Δ x/x, where, Δ x = change in dimension of the body and x = original dimension of the body. Strain is developed in response to the stress produced. More the stress, the more the strain.
Stress is the force applied to an object divided by its cross-section area. Therefore, the applied force must be known to determine the stress within an object. In addition, the cross-sectional area of the object is also important.
Stress is given by dividing the force by the area of its generation, and since this area (“A”) is either sectional or axial, the basic stress formula is “σ = F/A”.
elements or a collection of elements that form a system capable of supporting loads
a bridge in which the roadway deck is suspended from cables that pass over two towers; the cables are anchored in housings at either end of the bridge
an array of tension cables and compression rods that supports a structure; invented by Buckminster Fuller student Kenneth Snellson
a stretching force that pulls on a material
an action that twists a material
a rigid frame composed of short, straight pieces joined to form a series of triangles or other stable shapes, with all loads applied axially
a mechanical counterweight designed to reduce the effects of motion, such as the swaying of a skyscraper in the wind or in an earthquake
A measure of elasticity, equal to the ratio of the stress acting on a substance to the strain produced.
