Find the mass of each cubic meter of steel bars with different diameters

The formula is the square of the diameter (the diameter is in mm, and the calculated result is in kilograms), which is the weight of a meter long of a certain steel bar with a diameter, not cubic meters;

The three upstairs are not written correctly, the density on the first floor is missing, the second floor is missing a decimal point, the third floor is one less decimal point when it is replaced with kilograms, and the density of steel is not according to the specification.

No matter what the diameter of the rebar is a ton per cubic meter.

The weight of one meter of a certain diameter reinforcement = the square of the diameter (the diameter unit is mm, and the calculated result is in kilograms).

Different diameters have nothing to do with quality, and steel quality is only related to volume and density!

The density is a degree, and the volume can be multiplied!

Diameter (in mm) * Length (in m) = mass (in kilograms).

This is an empirical algorithm, and the exact algorithm is:

Radius square * length of rebar * density (the density of iron is 7900kg cubic meters).

Weight per meter: 0006165*Diameter squared.

I've answered it countless times, dizzy.

Mass = radius squared * length.

Multiply the square of the diameter by its weight per meter.

Then there's no need to talk about it.

Depend on! What's the problem? I don't know how.

Introduction to rebar: Rebar refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including round steel bars, ribbed steel bars, and torsion steel bars.

The steel bar for reinforced concrete refers to the straight bar or wire strip steel used for reinforced concrete reinforcement, and its shape is divided into two types: light round steel bar and deformed steel bar, and the delivery state is straight bar and disc round.

Summary. Hello, dear, the quality of the steel bar with a length of 5m and a diameter of 10mm is. The detailed calculation formula is as follows: there is a general formula for calculating the weight (weight) of the reinforcement: 1m reinforcement weight = squared; d is the diameter of the rebar; The weight of a rebar with a diameter of 10mm per meter is.

What is the mass of a steel bar with a length of 5m and a diameter of 10mm Hello, dear, the quality of a steel bar with a length of 5m and a diameter of 10mm is. The detailed calculation formula is as follows: there is a general formula for calculating the weight (weight) of the reinforcement: 1m reinforcement weight = squared; d is the diameter of the rebar; One meter quietly covers the weight of a steel bar with a diameter of 10mm.

Start the stove. Expand your knowledge: Steel reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which has a circular cross-section and sometimes a square with rounded corners. Including round steel bars, ribbed steel bars, and torsion steel bars.

The steel bar for reinforced concrete refers to the straight bar or wire strip steel used for steel or reinforced concrete, and its shape is divided into two types: light round steel bar and deformed steel bar, and the delivery state is straight bar and disc round.

Kiss! Hello! The quality of the steel bar with a length of 5m and a diameter of 10mm is the first thing to calculate the volume of the steel bar

The shape of the rebar is a cylinder, and its volume formula is v= r h, where r is the radius and h is the height, which can be approximated. Convert the diameter of 10mm to the radius: r = 10 2 = 5 mm = m Bringing the length of 5m into the above formula, the volume of the reinforcement is as:

v = 5 m Secondly, the density of the reinforcement needs to be calculated, which is usually 7850 kg m. Finally, multiply the volume of the reinforcement by the density to obtain the mass of the reinforcement: m = v 7850 kg, therefore, the mass of a steel bar with a length of 5m and a diameter of 10mm is about kg.

Solution: Because mass = density x volume, and the volume of a steel bar with a diameter of 20 cm per meter v = cubic meters, and the density of the steel bar = 7850 kg cubic meters, therefore, the mass of the steel bar = the density of the steel bar x the volume of the steel bar.

7850 kg cubic meters.

Kilogram. That is, the weight of this reinforcement is kilograms.

The diameter of 20mm steel bar is heavy yard per meter, and the grinding amount is kilogram.

Solution: Because mass = density x volume, and the volume of a steel bar with a diameter of 20 cm per meter v = cubic meters, and the density of the steel bar = 7850 kg cubic meters, therefore, the mass of the steel bar = the density of the steel bar x the volume of the steel bar.

7850 kg cubic meters.

Kilogram. That is, the weight of this reinforcement is kilograms.

First of all, calculate the state source to calculate its state buried cross-sectional area, x1 sail trace state = centimeters grams per meter gram,

Weight per meter (kg) = diameter of the rebar (mm) Diameter of the rebar (mm).

Weight per meter (kg) = diameter of the reinforcement (mm) The diameter of the reinforcement (mm), that is, the weight of the reinforcement is proportional to the square of the diameter.

The theoretical weight of steel is calculated based on the nominal size and density of the steel (in the past known as specific gravity), and the weight is called theoretical weight. This is directly related to the length dimensions, cross-sectional area and allowable deviation of the dimensions of the steel. Due to the allowable deviation of the steel during the manufacturing process, the theoretical weight calculated by the formula is different from the actual weight, so it is only used as a reference when estimating.

The diameter of 20mm steel bar is heavy yard per meter, and the grinding amount is kilogram.

Solution: Because mass = density x volume, and the volume of a steel bar with a diameter of 20 cm per meter v = cubic meters, and the density of the steel bar = 7850 kg cubic meters, therefore, the mass of the steel bar = the density of the steel bar x the volume of the steel bar.

7850 kg cubic meters.

Kilogram. That is, the weight of this reinforcement is kilograms.

Approximately. Steps to calculate the theoretical weight per meter of 20mm diameter steel bar:

The cross-sectional area of the steel bar is 1 meter, which is the volume of each meter of the steel bar. Then use the volume The density of the reinforcement is the mass of the reinforcement per meter.

20mm=20÷1000=

Volume per meter of reinforcement:

v=πr²h

According to the formula: m= v (mass = density volume).

The vertical density of the trousers of the steel bar here is calculated according to the large section.

A: The weight (mass) per meter is about.
