Question

i want to know the density of 16mm thick steel bar

Answer 1

Density of steel is 7850gms per cum

Mild steel has a density of 7.85 g/cm³

Volume of steel rod with diameter of 16mm and a length of 1m:

Volume = Pi x 0.82 x 100

Volume = 201 cm3

Mass = 201 x 7.85

Mass = 1577.85 g

Weight = 1.57785 x 9.82

Weight = 15.5 N
