Calculating Section weight of Mild steel angle

A mild steel angle of dimensions 35 mm x 35 mm x 5mm and is 20 feet long.

Can anybody detail me about the calculation of it's section weight?

Kind regards

You have to calculate the volume as length x cross-sectional area, then multiply by the density. You have to use consistent units; I'll use centimeters, and 7.9 g/cm³ for the density. Various grades of steel can differ slightly from this.

Dimensions 3.5 cm x 3.5 cm x 0.5 cm, by 609.6 cm long
Cross section area is 0.5 cm x (3.5 cm + 3.0 cm) = 3.25 cm²
Volume is 3.25 cm² x 609.6 cm = 1981.2 cm²
Mass is 7.9 g/cm³ x 1981.2 cm³ = 15651.5 g, or about 15.65 kg

You could work in any length units, but that will determine your volume units, and you need density in those units. The above approach generalizes to any constant shape, but the area may be more complicated to figure.

Different shape sections may be harder to calculate cross sectional area, but post #2 is a general guide.

Re: Calculating Section weight of Mild steel angle

For this typical cross section
you could use mensuration formulas for circles and rectangles and then combine the areas.

Cross section 0.6 cm*(5 cm + 4.4 cm) = 5.65 cm²
Length 609.6 cm
Volume 3438.14 cm³
Mild steel is about 7.85 g/cm³, so 26989 g or 26.989 kg
I would just round to 27.0 kg.
