What Is Meant By Cross Sectional Area

If you cut it.
What is meant by cross sectional area. For example a cylinder of height h and radius r has a π r 2 displaystyle a pi r 2 when viewed along its central axis and a 2 r h displaystyle a 2rh when viewed. Cross sectional analysis is a type of analysis where an investor analyst or portfolio manager compares a particular company to its industry peers. Cross sectional representing a plane made by cutting across something at right angles to its length.
Analysis of cross sectional data usually consists of comparing the differences among selected. A cross section is the two dimensional slice you would get by cutting through the object with a plane. Cross section views of the neck.
The cross sectional areais 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. Cross section area and volume. Cross sectional data or a cross section of a study population in statistics and econometrics is a type of data collected by observing many subjects such as individuals firms countries or regions at the one point or period of time.
Calculating a cross sectional area is an integral part of trenchless rehabilitation methods because based on this area the size of the lining or replacement pipe is determined. A cross sectional area is the area of the sliced portion of a 3d object such as a pipe. So all you need to know to be able to calculate the cross sectional area is its radius.
When a pipe is sliced perpendicular to its longest axis the cross sectional area will be calculated for the top part of the sliced portion which is a circle. The volume of the solid is defined as the integral of the area of the cross section. If cut the normal way.
For example the cross section of a cylinder when sliced parallel to its base is a circle. Volume by cross section. The cross sectional area of an object when viewed from a particular angle is the total area of the orthographic projection of the object from that angle.
