A unit cross-section, as defined by the SI system of measurement, is 1 metre2. So a column of air is all the air in a vertical column whose cross sectional area is 1 m2. The exact shape of the cross section is not defined but it is normally circular or a square.

What quantity is defined as deformative force per unit cross sectional area?

Stress is the quantity defined as deformative force per unit cross-sectional area. It is typically measured in units of force per unit area, such as newtons per square meter (N/m2) or pascals (Pa).


What is the cross sectional area of a wire?

If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.


What density current?

Current density is the amount of electrical current flowing in a unit of cross sectional area of that conductor. You'd look at the current flowing and the cross sectional area of the conductor and make a calculation from that. All you need do is decide on what unit of cross sectional area you wish to use. In wire, we usually use mils. Use the links below for more information.Density current is the measure of the density of flow of a conserved charge


What is a standard unit for measuring conductor cross-sectional area?

The standard unit for measuring conductor cross-sectional area is square millimeters (mm²). This unit is commonly used in electrical engineering and is helpful in determining the amount of current a conductor can safely carry.


How do you convert sq.ft. to cu.ft.?

You cannot convert sq. ft. into cu. ft. because, sq. ft. is the unit of area and the unit of volume. But if you know the cross sectional area of a cylinder in cu. ft. and its length (or height ) in ft. Then you can find its volume in cu. ft. by multiplying cross sectional area and the ;length (or height).


What is resistivity of material?

the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"


What is the difference between cross sectional area and diameter of power cable?

Cross section is the surfave area of the cable if you imagine it cut into ... gauge and diameter are basically the same thing, although the unit of measurement are different.


How can you calculate the unit weight of MS squre or ractangular pipe?

Cross sectional area (square metres) * 7850 = kilograms per metre length.

What is gram per millimeter?

It is a unit of measurement for linear density. It is usually used for objects with a constant and small cross-sectional area such as bars, rods or wires.


Why hollow shaft is used for propeller shaft?

Because the load taking capacity of hollow shaft is more as the load per unit area is lesser due to the lesser cross sectional area.


A jet of water of cross sectional area A and velocity V impinges normally on stationary flat plateThe mass per unit Volume of water is roh By dimensional analysisdetermine an exression for force F?

The force F can be expressed as F = ρ * A * V^2. This is derived by considering the balance of forces in terms of the primary variables of mass density (ρ), cross-sectional area (A), and velocity (V) through dimensional analysis. The force is proportional to the density, cross-sectional area, and the square of the velocity of the jet of water.
