45 How do you calculate the weight of round bars? What is the formula?

It is a plate.

The density of the steel is not round.

The density, although the friend's 45*45 is wrong, but the density is right, and the round steel is generally calculated (whether it is a plate or a round bar, the weight calculated according to the density is different from the actual one). It should be the diameter of the round bar * diameter * the height (length) of the round bar * the result is to eliminate the last 6 decimal points and then the unit is calculated kg, or the unit can be calculated as g) For example, the diameter is 80mm and the height is 1000mm, which is 80 * 80 * 1000* So the actual weight is about equal to 39kg (generally greater than the actual weight, usually it is counted as a plate, and it is rarely counted as a round bar, I don't know if it is calculated like this, it is possible that I am also mistaken. 45 We usually call it "medium carbon", and most of it is only used in molds.

For example, the weight per meter of round steel with a diameter of 45 mm can be calculated as follows:

This is a simplified formula, the full formula should be: the square of the diameter (in millimeters) 4 7850 10 to the minus 6 power, which can be simplified to the above formula.

The square of the radius r * length * density (approximately, the units are converted by themselves.)

Downstairs wrong, 45 is the type of steel, which is medium carbon high-quality high-strength steel, not round steel diameter.

45 * 45 * That is to say, the weight of 6 yuan steel =

The formula for calculating the weight of round bars is: weight of round bars = base area x height (or length) x material density = volume x material density.

For example: diameter d=18mm= then:r= length h=300mm=30cm

The density of the round bar is found to be m=

Then: the weight of the round bar g= r2hm=

Extended Materials. Round steel refers to a solid strip of steel with a circular cross-section. Its specifications are expressed in diameter, in millimeters (mm), such as "50mm" means a round bar with a diameter of 50 mm.

The difference between round bars and other steel bars:

1. The appearance is different, the appearance of the round steel is light and round, no lines and no ribs, and the surface appearance of other steel bars has carved lines or ribs, which causes the adhesion between the round steel and the concrete to be small, and the adhesion between other steel bars and concrete is large.

2. The composition is different, round steel (first-class steel) belongs to ordinary low-carbon steel, and other steel bars are mostly alloy steel.

3. The strength is not the same, the strength of the round steel is low, and the strength of other steel is high, that is, the round steel with the same diameter and size is compared with other steel bars, the tensile force that the round steel can withstand is smaller than that of other steel bars, but the plasticity of the round steel bar is stronger than that of other steel bars, that is, the round steel has a large deformation before being pulled off, and the deformation of other steel bars before being pulled off is much smaller.

Diameter Diameter Length Hello, what is the diameter of the round bar?

To find the cross-sectional area, multiply by the square of the radiusPi, to get the cross-sectional area (the area of the circle is s= r 2), find the volume, multiply the cross-sectional area by the length, and get the volume (of the cylinderVolume formulais v=sh). Find the weight and multiply it by the density of the steel of 7860 kg cubic meters to get the weight of the round bar No. 45 (the formula for mass m = v).

Round steel refers to a solid strip of steel with a circular cross-section. The specification is expressed in millimeters of diameter, e.g. "50" means a round bar with a diameter of 50 mm. 45 Round bars are divided into three types: hot-rolled, forged, and cold-drawn. Wow.

The specifications of hot-rolled round bars are brother trace millimeters. Among them: most of the small round steel of millimeters is bundled with straight bars**, which is often used as steel bars, bolts and various mechanical parts; Round bars larger than 25 mm are mainly used to make mechanical parts or seamless steel pipes. Dam.

The formula for calculating the weight of a round bar No. 45 W is equal to F multiplied by L multiplied by 1 divided by 1000where is equal to 7.85g per cm3, where f is the cross-sectional area of the steel, where f is equal to , 45 divided by 2 square mm, and l is the length of the steel. Weight is a measure of the magnitude of an object subjected to gravity, weight and mass are different and the unit is Newton.

It is a fundamental property of an object that gravitationally pulls on the earth.

Below, the weight of a substance with a mass of 1 kg is 9.8 Newtons.

Weight of the contents

In the past in the field of physics, there was a suggestion that the magnitude of the gravitational force on the object near the surface of the earth is called the weight, and the object on the surface of the earth, in addition to the gravitational force of the earth on it, will also be affected by the inertial centrifugal force due to the rotation of the earth, and the magnitude of the combined force of these two forces is called the weight of the object.

The gravitational force experienced by an object is its own weight, and there are many explanations for weight, for example, weight is gravity, and the weight of an object is the gravitational pull of the earth on the object.

Weight is the amount of gravity exerted on an object, and weight is the force that pulls a vertical suspension rope or presses on a horizontal support when the object is at rest.

Some emphasize that weight is gravity, which is a vector, and their essence is gravity, and some emphasize that gravity is not a vector, and weight is the magnitude of gravity, which is a scalar quantity.

There are also the laws of measurement as the definition of weight, and these different definitions are just different interpretations, and there is no right or wrong.

Under the gravitational pull of the earth, weight and mass are equivalent, but the units of measurement are different, the weight produced by the external force of a substance with a mass of 1 kilogram is 9.8 Newtons is called 1 kilogram weight, and the unit of mass is generally used instead of weight, implicitly multiplied by gravitational acceleration.

The formula for calculating the theoretical weight of round bars: diameter diameter weight (kg m).

Round bars are divided into three types: hot rolled, forged and cold drawn. The size of the hot-rolled round bar is 5 5 250mm. Where:

5 5 25mm small round steel is mostly supplied in straight bundles, which are often used as steel bars, bolts and various mechanical parts; Round steel above 25 mm is mainly used in the manufacture of mechanical parts, seamless steel pipe billets, etc.

Notes:

Ordinary carbon structural steel, also known as ordinary carbon steel, has a wide range of restrictions on carbon content, performance range, and the content of residual elements such as phosphorus and sulfur. In our country and some countries, according to the conditions of the guarantee of delivery, it can be divided into three categories: Class A steel (Class A steel) is a steel that guarantees mechanical properties.

Grade B steel (B-grade steel) is a type of steel that guarantees a chemical composition.

Special steels (C-class steels) are steels that guarantee both mechanical properties and chemical composition, and are often used in the manufacture of more important structural parts. The most produced and used steel in China is A3 steel (A-grade No. 3 steel), which has a carbon content of about 0 20 and is mainly used for engineering structures.

Some carbon structural steels also add trace amounts of aluminum or niobium (or other carbide-forming elements) to form nitride or carbide particles to limit grain growth, strengthen the steel, and save steel. In China and some countries, in order to meet the special requirements of professional steel, the chemical composition and properties of ordinary carbon structural steel have been adjusted, resulting in a series of ordinary carbon structural steel (such as bridge, construction, reinforcement, pressure vessel steel, etc.).

Meters long, diameter 50 What is the weight.

How many kilograms is 50 round bar 1 meter? I guess it's kilograms. How is the chain calculated, and why?

Because everyone knows that the kilogram is a unit of weight, which corresponds to the decimeter. The 50 round steel is a diameter of 50 mm Huai Chao round steel, 50 mm is equal to the shed clear yard meter, 1 meter is equal to 10 decimeters. The formula for calculating the weight of a round bar is radius multiplied by radius multiplied by length multiplied by specific weight, according to the formula it is equal to.

So 50 round bars weigh 1 meter is.
