Pronunciation (US):
Dictionary entry overview: What does cross section mean?
• CROSS SECTION (noun)
The noun CROSS SECTION has 3 senses:
1. a section created by a plane cutting a solid perpendicular to its longest axis
2. a sample meant to be representative of a whole population
3. (physics) the probability that a particular interaction (as capture or ionization) will take place between particles; measured in barns
Familiarity information: CROSS SECTION used as a noun is uncommon.

When the length and area of cross section both are doubled then its resistance?
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
What are mathematical relationship between resistance and specificconductivity constant?
Cell constant(C) = Resistance(R) X Specific Conductivity(K)
How do you work out resistance with voltage and joules?
Resistance of a conductor is defined by the specific resistivity, area of cross section and the length of the conductor. R = rL/A, where R is resistance in OHMs, r is specific resistance, L length in mm, A is area of cross section in sq mm
What is the cross-section area of a wire if its outside diameter is 0.0625 inch?
It is approx 0.003068 square inches.
Relation between tensile stressbending moment and section of modulus?
The relation between bending moment and the second moment of area of the cross-section and the stress at a distance y from the neutral axis is stress=bending moment * y / moment of inertia of the beam cross-section
If they give me the height of a prism and the cross-section area how do I find the volume?
Multiply the cross-section area by the height.
How do you find volume of a box with uniform cross section if only height is given?
You need to know the area of that cross-section. Once you have that number, the volume of the box is the product of (cross-section area) x (height).
What is the formula for cross section area for square?
The formula for cross section area of a square is very easy to use. Measure the length of one side of the square it. If you are doing the cross section area of a rectangle, measure both sides and multiply them together.
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
How you find the volume of a trapezoidal 3D section?
Volume = area of cross-section*length
What is the volume of the prism describe how you found the volume?
To find the volume of a prism you first need to know the area of cross section. Then, Volume of prism = area of cross section x length.
What is a meant by cross section?
Imagine that you wanted to cut a globe or a sphere exactly in half. When you looked at the cut you would see an exact circle on both pieces. This area would be the cross-section. You could work out the area of this cross-section by using A = Pi X r squared. But be careful. Don't assume that the cross sectional area is the same no matter where you cut. If you cut the globe at some other point, say near to the edge, the cross-section (the circular area that you would see) would be a lot smaller. You would come across a uniform cross-section if you cut a cable. No matter where you cut the cable the cross-section should be roughly the same. Also cross section doesn't have to be circular. The cross-section you get really depends on the original shape you are dealing with. If you cut a cube in half, you would get a square cross-section. So I guess you could imagine the term as applying to cutting across (hence cross) something to reveal 2 sections (hence section).
How do you calculate the cross sectional area of cable?
Simply work out the area of a section of cable.........
What is the area of the cross section of a sphere that is 3 units from the center of the sphere?
The cross section at this point forms a circle and its area is pi/32 which equals 9*pi square units. * * * * * Not quite. If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
When the length and area of cross section both are doubled then its resistance?
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
When the length and area of cross-section both are doubled then its resistance?
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
the area of a cross section of a prism with a cross section which is a regular hexagon is 10.4m^2. the volume of the prism is 8.84m^2. calculate the height of the prism?
just not to confuse you, here is the question more clearer: A prism has a cross section that is a regular hexagon The area of the cross section is 10.4m^2. The volume of the prism is 8.84m^2. Calculate the height of the prism.
