✅Derivation Of (d²/162) 📌Density Of Steel = 7850 kg/m³ Unit Conversion of 7850 kg/m³ 7850 kg / m³ = 7850 kg / (m x m x m) = 7850 / (1000 x 1000 x 1000) kg/m³ 📌Formula For Calculating Weight Of Bar Weight = Volume x Density = (Area x Length) X Density 📌Formula For Calculating Weight Of Bar = (π/4) x d² x Length x Density = (3.14/4) x d² x 1000 x [(7850) / (1000 x 1000 x 1000)] = d² x 0.00616225 = (d² / 1) x (0.00616225 / 1) = (d² / 162.29) ≅ (d²/162) @civil_by_yahya_sir 🔰𝐃𝐢𝐬𝐜𝐨𝐯𝐞𝐫 𝐄𝐱
