An angle iron is a length of iron or steel, with an L-shaped cross-section, used as a structural support.
radius of gyration = sqrt(Moment of inertia/cross section area) Regards, Sumit
We know the formula D2/162 which is being used for calculate unit weight of reinforcement per meter.Here I am willing to explain how it has been arrived D2/162 (Note: D unit is in MM)Weight of bar per meter = Area of steel bar X Density of steel x Length of bar= (3.14 x D2/4) x 7850 kg/m3 x 1 m= D2 X 6162.25/(1000x1000)= D2 X (0.006162)= D2 X 1/(0.006162)-1= (D2/162.28)The actual value is D2/162.28Kindly note that this function is only applicable for circular shape steel which density is 7850kg/m3
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)
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.
by calculating I=1/12bh3
force/area = stress (it's the same as pressure)
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.
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
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.
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.
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.
Cannot determine without also knowing the gauge or other equivalent cross-sectional area.
ferrite calculate formula?
as every size bar differ in diameter and possibly type, the reinforcement steel is measured in kilograms per meter, say 8.5kg/m. the steel weight is actually calculated, as a % of the cross-sectional area. different applications have different minimum % steel required, roughly work on 1%. the sum of the bars cross sectional area at each support and spans are seperately calculated and compared to the cross sectional area of the concrete, hence expressed as a %.
