Question

unit mass of steel?​

Answer 1

Answer:

If you have 10 cm3 of steel with a density of 7.85 g/cm3, the mass would be 78.5 g or 0.0785 kg. You can convert mass to weight by multiplying it by 9.8 m/s2 to get 0.77 newtons of steel. You can also determine the steel density using its specific gravity.

Answer 2

Answer:

Steel bar is the ratio of the weight of steel per unit volume.

Explanation:

• Steel's unit mass is calculated as the weight of steel divided by its volume.
• It is expressed in kilogram or pounds per cubic metre..
• Steel has a unit mass of 7850 kg/m3, which is equal to 490 lbs /ft3.

Steel:

• Steel is used to construct structural elements such as building slabs, footings, foundations, and columns.
• The primary usage of the steel bars is as reinforcement to increase the tensile strength of concrete constructions.
• One of the most popular building materials is steel. It is equally crucial to determine the steel bar's unit weight before using it.

The formula for calculating the weight of the flat bar,

Weight = Volume × Density

Weight of flat steel bar= (Length × Width × Thickness) × Density of
