Weight =  Volume x density Since its cylindical shape Volume of bar = pi()*h*(d²)/4 mm³ where h is height of cylinder bar d is diameter in mm Weight density of steel = 7850 kg/m³ Here we considering for 1m length, so h = 1m Volume of bar = pi()*h*(d²)*(10⁻⁶)/4 m³ = pi()/4*h*(d²)*(10⁻⁶) Here we have … Continue reading How to calculate weight of Mild Steel bar →
