Derivation of steel weight calculation D²/162
Derivation of steel weight calculation D²/162 Derivation : W = c/s area × density of steel × length of steel = (π/4 × D²) × 7850 ×1 = (3.14 × D²/4) × 7850 = 6162.25 D² =D²/ 1.6227 × 10-⁴ [ 1m = 1000 mm ] = D²/ 1.6227 × 10-⁴ × 1000² = D²/ 162.27 W = D² / 162 https://youtu.be/v3_qNReDvRs
