A typical cross-section drawing of a roadway. The cross section of a roadway can be considered a representation of what one would see if an excavator dug a trench across a roadway, showing the number of lanes, their widths and cross slopes, as well as the presence or absence of shoulders, curbs, sidewalks, drains, ditches, and other roadway ...
Thus, a plane section is the boundary of a cross-section of a solid in a cutting plane. If a surface in a three-dimensional space is defined by a function of two variables, i.e., z = f ( x , y ) , the plane sections by cutting planes that are parallel to a coordinate plane (a plane determined by two coordinate axes) are called level curves or ...
An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
Longitudinal – spanning the length of a body. Lateral – spanning the width of a body. The distinction between width and length may be unclear out of context. Adjacent – next to; Lineal – following along a given path. The shape of the path is not necessarily straight (compare to linear).
These "synthetic" longitudinal gradients can then be used to reach a sufficient drainage gradient in sections where the cross slope is close to zero. Another option to minimize crash risk due to low DG at the entrance or exit of banked outercurves is to move the superelevation further from the curve and out to a straight road section.
In other words, the third dimension, so the longitudinal cross-section can be represented as the projection of the transversal cross-section in the infinity of the horizon. An example of 2 + 1 ⁄ 2 -D processing, can be 2 + 1 ⁄ 2 -D microextrusion , where, thanks to an optimal control of the process, the obtained extrudate, which is ...
This is done by having a chord of 100 feet (30.48 m) connecting to two points on an arc of the reference rail, then drawing radii from the center to each of the chord's end points. The angle between the radii lines is the degree of curvature. [ 10 ]
