There are a lot of students who want to the answer for the question of what is D2/162. This is a special content for all those students who want to the answer for this question.
As we know that weight of steel bar per meter = Volume of steel x Density of steel
Weight of steel bar per meter = πD2/4 x 1000 mm x 7850 kg/ 1000 mm x 1000 mm x 1000 mm
Weight of steel bar per meter = 3.14D2/4 x 7850/1000 x 1000 = 0.785D2 x 0.00785
Weight of steel bar per meter = 0.0061622 x D2 = D2/1/0.0061622 = D2/162.27
Hence Proved.
