A cross-section is a slice through any object which shows its layer structure. In the context of the technical examination of painting it is a minute sample of paint layers.
What is cross section with examples?
A cross-section is a shape that is yielded from a solid (eg. cone, cylinder, sphere) when cut by a plane. For example, a cylinder-shaped object is cut by a plane parallel to its base; then the resultant cross-section will be a circle. So, there has been an intersection of the object.
What is cross section of a shape?
A cross-section is a plane section that is a section of a three-dimensional object that is parallel to one of its planes of symmetry or perpendicular to one of its lines of symmetry. Describe shapes formed by cross-sections (square, rectangle, triangle, etc).
What is the meaning of cross section area?
The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object – such as a cylinder – is sliced perpendicular to some specified axis at a point. For example, the cross-section of a cylinder – when sliced parallel to its base – is a circle.
How do you find cross sections?
The volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h. Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.
What is a cross section of a solid?
A cross section of a solid is a plane figure obtained by the intersection of that solid with a plane. The cross section of an object therefore represents an infinitesimal “slice” of a solid, and may be different depending on the orientation of the slicing plane.
What is another word for cross section?
In this page you can discover 14 synonyms, antonyms, idiomatic expressions, and related words for cross-section, like: transversion, transection, cross-sectional, parallelepiped, proportion, random-sample, sample, sampling, barn, semicircle and subimages.
What is cross section and longitudinal section?
Longitudinal studies and cross-sectional studies are two different types of research design. In a cross-sectional study you collect data from a population at a specific point in time; in a longitudinal study you repeatedly collect data from the same sample over an extended period of time.
What is wire cross section?
Most wire is made with a circular cross section of some particular radius and diameter. Then we define the cross sectional area simply as the square of the wire’s diameter in mils and call that our area in units of “circular mils.” This makes number handling ever so much easier.
What is meant by typical section?
Typical sections are detailed cross section depictions of the highway’s principal elements that are standard between certain station or milepost limits. These sections are the basis for construction details and information shown on the various plan sheets throughout the plans package.
How are cross sections used in real life?
Cross sections are used in architecture and engineering quite often. By understanding cross sections and how to cut a certain object to create the desired shape, we are able to construct amazing buildings and other inventions. Another common example of cross sections are the cross sections created when sawing wood.
What is a cross-section of a prism?
A prism has a cross-section which is exactly the same shape and size throughout its length. A triangular prism has a triangular cross-section. To calculate the volume of a prism, first calculate the area of the cross-section.
Is it cross-section or cross-section?
A cross-section of an object is what you would see if you could cut straight through the middle of it.
What is the cross-section of a rectangular pyramid?
Glossary Terms. A cross section is the new face you see when you slice through a three-dimensional figure. For example, if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section.
What is the cross section of a pentagonal prism?
A pentagonal prism is a type of heptahedron, which is a polyhedron with seven plane faces. A pentagonal prism can also be called a five-sided polygon prism. The cross-section of a pentagonal prism is a pentagon.
What is a cross section of a cube?
Slicing Solids A cross section is the face you get when you make one slice through an object. Below is a sample slice through a cube, showing one of the cross sections you can get. The cross section cannot contain any piece of the original face; it all comes from “inside” the solid.
What is the opposite of a cross section?
What is the opposite of cross-sectional? common collective cumulative combined overall shared assembled broad collated communal.
What is a antonym for cross section?
Princeton’s WordNet. cross sectionnoun. a section created by a plane cutting a solid perpendicular to its longest axis. Antonyms: lengthways, lengthwise.
How do you use cross section in a sentence?
1 The contestants are drawn from a cross section of society. 2 We interviewed a wide cross section of people. 3 The demonstration provided a platform for a broad cross section of speakers. 4 The study group was selected from a broad cross section of the population.
What is a cross section or profile?
A graphic representation of the sections that are in a linear work, on cutting the axis of the aforementioned work with vertical planes perpendicular to it and defining the trace in elevation.
What is latitudinal section?
Latitudinal Sections (Side Views) Each section extends from south (on the left) to north (on the right). In other words the view direction is from east toward the west. The topmost profile is the west-most.
What is area of cross section in electricity?
Cross section represents a plane made by cutting across something at right angles to its length. If you cut a wire and look straight on you will see a circular plate. The area of this cross section is called its area of cross section.
How do I calculate voltage drop?
To calculate voltage drop: Multiply current in amperes by the length of the circuit in feet to get ampere-feet. Circuit length is the distance from the point of origin to the load end of the circuit. Divide by 100. Multiply by proper voltage drop value in tables. Result is voltage drop.
