Q4. What is the unit weight of 1. 32mm dia steel 2. 25mm dia steel 3. 20mm dia steel 4. 16mm dia steel 5. 10mm dia steel 6. 08mm dia steel 7. 06mm dia steel?
Ans. 
Unit weight of different diameters of steel bars
• Unit weight of steel = D^2/162.2 kg/m, where D is the diameter of the steel bar in mm

• Calculate unit weight for each diameter provided in the question

• 32mm dia steel: 32^2/162.2 = 6.31 kg/m

• 25mm dia steel: 25^2/162.2 = 3.85 kg/m

• 20mm dia steel: 20^2/162.2 = 2.47 kg/m

• 16mm dia steel: 16^2/162.2 = 1.57 kg/m

• 10mm dia steel: 10^2/162.2 = 0.62 kg/m

• 08mm dia steel: 08^2/162.2 = 0.39 k
