What is formula to calculate the weight of steel bar?

volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)


What is the weight per meter of 140x140x12.5 shs mild steel?

To calculate the weight per meter of a 140x140x12.5 SHS (Square Hollow Section) mild steel, you would need to first calculate the cross-sectional area (A) of the SHS using the dimensions provided. Then, you can multiply the cross-sectional area by the density of mild steel (7,850 kg/m^3) to get the weight per meter.

How calculate weight per meter of 45x45x5 angle?

To calculate the weight per meter of a 45x45x5 mm angle, you first determine the volume of the angle. The formula for the volume can be approximated as the cross-sectional area multiplied by the length. The cross-sectional area of the angle can be calculated by considering the two legs and the thickness, and then multiplying by the length (1 meter). Finally, multiply the volume by the density of the material (typically for steel, it's around 7850 kg/m³) to get the weight per meter.


How should we calculate weight of ismc?

To calculate the weight of an ISMC (Indian Standard Medium Channel), you can use the formula: Weight (kg/m) = (Area of cross-section (cm²) × Length (m) × Density of steel (approximately 7850 kg/m³)) / 10000. First, determine the cross-sectional area from the ISMC specifications, then multiply by the length in meters and the density of steel. This will give you the weight per meter, which can then be multiplied by the total length to obtain the total weight.


Cross sectional area of 176.6mm2. what is the formula for finding the working tensile stress in the steel rod. also the formula for then finding the strain resulting from the working tensile stress?

force/area = stress (it's the same as pressure)


What is formula to calculate the area of steel bar?

The formula to calculate the area of a steel bar is A = πr^2, where A represents the area and r is the radius of the steel bar. This formula assumes that the steel bar is circular in shape. If the steel bar is a different shape, such as rectangular or square, the formula to calculate the area would be different based on the dimensions of the bar.


How do you calculate cross sectional area for steel bars?

Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.Measure the diameter = d cm. Then radius = d/2 cm and cross sectional area = pi*r2 cm2.


What is the difference between steel rod and steel bar?

Rod is circular in shape. If u look it from where it starts, i.e. its cross sectional view it will be circular. It may or may not be hollow. Bar's cross sectional view will be a quadrilateral. Shivangini


How do you calculate the area of structural steel beams?

To calculate the area of structural steel beams, you typically use the formula for the cross-sectional area, which is determined by the shape of the beam. For common shapes like I-beams or channels, you can find the area by referencing standard tables that provide dimensions for various beam profiles. Alternatively, you can calculate the area by measuring the width and height of the beam and applying the appropriate geometric formula (e.g., for an I-beam, subtract the areas of the flanges and web). Ensure to use consistent units for accurate results.


How do you calculate weight of mild steel when sectional area given?

Calculate the volume first by multiplying the cross sectional area with length.Multiply the volume with density of mild steel which will give the weight.The density of Mild steel is 7850 kg/ m3e.gCalculate the weight of 2 m rod having cross sectional area of 5 m2Volume = 2x5 = 10 m3Weight = 10 x 7850 = 78500 kgBe specific that same units are used all around the calculations.


How do you calculate cross sectional area in rebar?

Most rebar (steel reinforcement bar) is approximately round. Measure the diameter of the bar, that is, the thickness of the bar. Divide the measurement by 2 to get the radius. Use the formula pi x r2 (3.14 x radius x radius) to get the cross sectional area. The formula works for all measurement units whether they are inches, millimeters, centimeters or others. An alternative is to use (pi x d^2)/4. (3.14x diameter x diameter divided by 4) You do not then need to divide the original diameter.
