Engineering Fold / Fold-Out Typically used for ledger size sheets (11" x 17") that are bound in proposals or technical documents. The sheet is folded just off-center then the larger panel is folded in half on itself - the narrowest panel can be pulled out to expand the sheet to its full width, while the left edge is free to be bound in a book or binder.

What is a fold in 3D geometry?
Fold terminology in three dimensions. A fold axis, “is the closest approximation to a straight line that when moved parallel to itself, generates the form of the fold.” (Davis and Reynolds, 1996 after Donath and Parker, 1964; Ramsay 1967). A fold that can be generated by a fold axis is called a cylindrical fold.

What is a paper disc?
An illustrated paper disc or circle is attached to a page using string, paper, or grommets and revolves around a central pivot. As the reader turns the wheel, the discs align images and information. The disc can be perforated to reveal designs underneath. The word volvelle is derived from the Latin verb, volvere, to turn.
What is a volvelle?
of a medieval monastery. The earliest books with movable parts recorded and communicated information and also calculated data. Illustrated volvelles or wheels were super- imposed on the surface of a page, turning to align data to calculate the position of the stars, church calendar, astrological signs, and the like. It is thought that the Benedictine monk Matthew Paris employed volvelles to determine ecclesiastical dates as early as the 13th century, as did the Catalan mystic and poet Ramon Llull shortly thereafter to explain his theory of spirituality and truth.

The story of movable and pop-up construction begins within the walls of a medieval monastery. The earliest books with movable parts recorded and communicated information and also calculated data. Illustrated volvelles or wheels were super-imposed on the surface of a page, turning to align data to calculate the position of the stars, church calendar, astrological signs, and the like.

Who created the Jolly Jump Ups?
Jolly companions (1896) and participate in the adventures of the Jolly Jump-Ups family, a series of stage-set pop-ups created by Geraldine Clyne (1930s-1960s). Ernest Nister, a Nuremberg publisher and innova- tor of pop-up and movable mecha- nisms, regularly features well-dressed Victorian children in stories like his Circling surprises (1901), a revolving wheel slat book. A visit to the zoo becomes an exciting adventure in Nister’s The model menagerie (1895), when caged animals magically lift into three-dimensional forms as each page is turned. Children enjoy a trip to the circus in paper engineer Julian Wehr’s Animated circus book (1943), in which his pull-tab system allows circus ani- mals and performers to move across a page in all directions.
What is the definition of fold?
Definition of Fold: It is frequently seen that the strata forming the earth’s crust have been not only tilted out of the horizontal but also bent and buckled into folds. Such a fold may range from microscopic crinkle to great arches and troughs even up to 100 kms across.
What are the parts of a fold?
Parts of a Fold: In a series of folds it is evident like waves. They consist of alternate crests and troughs. The crest of the fold is termed as anticline while the trough is called synclines. An anticline and syncline constitute a fold.
What does isoclinal fold mean in Greek?
In Greek Isoclinal fold means the two limbs dip in the same direction but at the same angle.
What is a simple fold, which is convex upwards?
3. Structural Terrace: A bed, which is inclined in one direction, may become more or less flat at one place. 4. Anticline and Syncline: ADVERTISEMENTS: Anticline is simple fold, which is convex upwards. In Greek it means opposite inclined. In this fold the limbs dip always from each other.
Which features aid in finding out the stratigraphic top of a bed?
4. In case of overturned and isoclinal folds, where all the limbs dip in the same direction, detailed observations are necessary to identify synclines and anticlines. The features which aid in finding out the stratigraphic top of a bed and hence the synclines and anticlines are drag folds, rock cleavage, cross-bedding, symmetrical ripple marks and graded bedding.
Why are folds important?
3. Folds are also important to a water supply engineer specially when he has to select a suitable site for digging wells for water supply purpose. It has been observed that if the excavation of a well is done through impervious strata it will not yield any amount of water. If another well is excavated through previous strata it will yield abundance of water.
Why should a site be avoided when a project is folded?
For a major project like a dam, tunnel, railway station, etc., a site which is highly folded should be avoided because the engineer may have to face much troubles sooner or later as folds are easily fractured even due to a slight disturbance. 2.

What is a fold in rock?
In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deform ation. Folds in rocks vary in size from microscopic ...
How does folding occur?
Typically, folding is thought to occur by simple buckling of a planar surface and its confining volume. The volume change is accommodated by layer parallel shortening the volume, which grows in thickness. Folding under this mechanism is typical of a similar fold style, as thinned limbs are shortened horizontally and thickened hinges do so vertically.
Why do rocks fold into hinges?
Layers of rock that fold into a hinge need to accommodate large deformations in the hinge zone. This results in voids between the layers. These voids, and especially the fact that the water pressure is lower in the voids than outside of them, act as triggers for the deposition of minerals. Over millions of years, this process is capable of gathering large quantities of trace minerals from large expanses of rock and depositing them at very concentrated sites. This may be a mechanism that is responsible for the veins. To summarize, when searching for veins of valuable minerals, it might be wise to look for highly folded rock, and this is the reason why the mining industry is very interested in the theory of geological folding.
How are folds formed?
Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault ( fault bend fold ), at the tip of a propagating fault ( fault propagation fold ), by differential compaction or due to the effects of a high-level igneous intrusion e.g. above a laccolith .
How does deformation occur in layered rocks?
When a sequence of layered rocks is shortened parallel to its layering, this deformation may be accommodated in a number of ways, homogeneous shortening, reverse faulting or folding. The response depends on the thickness of the mechanical layering and the contrast in properties between the layers. If the layering does begin to fold, the fold style is also dependent on these properties. Isolated thick competent layers in a less competent matrix control the folding and typically generate classic rounded buckle folds accommodated by deformation in the matrix. In the case of regular alternations of layers of contrasting properties, such as sandstone-shale sequences, kink-bands, box-folds and chevron folds are normally produced.
What is the inflection point of a fold?
The inflection point of a fold is the point on a limb at which the concavity reverses; on regular folds, this is the midpoint of the limb. Flank & hinge. The axial surface is defined as a plane connecting all the hinge lines of stacked folded surfaces.
What is a fold shape?
A fold can be shaped like a chevron, with planar limbs meeting at an angular axis, as cuspate with curved limbs, as circular with a curved axis, or as elliptical with unequal wavelength .
