Can a cross section be a point?

If the cutting plane is perpendicular to a line joining the centers of two opposite faces of the cube, the cross-section will be a square, however, if the cutting plane is perpendicular to a diagonal of the cube joining opposite vertices, the cross-section can be either a point, a triangle or a hexagon.

Can a cross section be a single point?

A “slice” of log. When a plane intersects a solid figure, the cross sectional face may be a point, a line segment, or a two-dimensional shape such as, but not limited to, a circle, rectangle, oval, or hexagon. The plane is tangent to the sphere, intersecting in only one point.

Can a point be a cross section of a sphere?

Spheres are perfectly round geometric objects. Spheres are NOT polyhedra. The intersection of a plane with a sphere is a circle (or a point if tangent to sphere). All cross sections of a sphere are circles.

What is considered a cross section?

1. a section made by a plane cutting anything transversely, esp. at right angles to the longest axis. 2. a piece so cut off.

Can a cross section be a circle?

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.

What is a cross-section on a topographic map?

A topographic map is a flat map representing elevations with contour lines. These contour lines connect locations with the same altitude above sea level. A cross-section is a side-on profile of a specific line that we want to draw on the map.

Is cross-section hyphenated?

You have already learnt the truth: they are variants. I would always use cross-section. Omission of the hyphen could create ambiguity. A cross section of Americans hate queueing could be understood to mean A bad-tempered number of Americans. . .

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 another word for cross-section?

Is a cross-section horizontal or vertical?

Horizontal cross-section: If the intersecting plane is parallel to the base of the solid figure, we get the horizontal cross-section of the figure. Vertical cross-section: If the intersecting plane is perpendicular to the base of the solid figure, we get the vertical cross-section of the figure.

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 cross section of wire?

The cross-sectional area of the wire A is the area of a circle of radius r, or of diameter d = 2r: A=πr2=π(d2)2. Then we substitute the expressed cross-sectional area into the previous relation to obtain the final formula for calculating the resistivity of the wire: ρ=RAl=Rπ(d2)2l. ρ=πRd24l.

How do you teach cross-sections?

Video quote: Different parallel cuts here so we already talked about the rectangular prism if you cut parallel notice how the Red Square is parallel to the yellow faces or the yellow base with a rectangular prism.
