Calculate weight of rectangular bar

What is a rectangular bar?

A rectangular steel bar is a kind of solid material with a rectangular shape, commonly used in the construction industry, machinery manufacturing and other fields. To calculate the weight of a rectangular steel bar, you can use the formula:

𝑃 = 𝐿 × 𝐴 × Spec Weight ı ˊ I am

Where:

  • 𝑃 is the weight of the bar in kg;
  • 𝐿 is the length of the bar in meters;
  • 𝐴 is the cross-sectional area of ​​the bar in 𝑚 two ;
  • The specific weight of steel is approximately 7850 kg/m³.

The cross-sectional area of ​​a rectangular bar is given by:

𝐴 = 𝐿 𝑎 𝑟 𝑔 𝑢 𝑟 𝑎 × 𝐴 𝑙 𝑡 𝑢 𝑟 𝑎

Therefore, to calculate the weight of a rectangular steel bar with width 𝐿 𝑤 , height 𝐿 ℎ and length 𝐿 , the formula would be:

𝑃 = 𝐿 × ( 𝐿 𝑤 × 𝐿 ℎ ) × 7850

For example, if we have a rectangular bar with a width of 50 mm (0.05 m), a height of 20 mm (0.02 m) and a length of 1 meter, the calculation would be:

𝑃 = 1 × ( 0 , 05 × 0 , 02 ) × 7850

𝑃 = 1 × ( 0 , 001 ) × 7850

𝑃 = 7 , 85 kg

Therefore, the weight of the rectangular steel bar with these dimensions would be approximately 7.85 kg.
