Flange = 150 mm x 5 mm x 1 m
Web = 140 mm x 10 mm x 1 m
Volume of Flange = 150 mm x 5 mm x 1 m
= 0.150 m x 0.005 m x 1 m
= 0.00075 m3
There are two number of flange,
= 0.00075 x 2
= 0.0015 m3
Volume of Web = 140 mm x 10 mm x 1 m …..(150 mm – 10 mm = 140 mm)
= 0.140 m x 0.010 m x 1 m
= 0.0014 m3
Volume of ‘I’ Section = Volume of Flange + Volume of Web
= 0.0015 + 0.0014
= 0.0029 m3
Weight of ‘I’ Section = Volume of ‘I’ Section x Density of steel
= 0.0029 x 7850...........(Density of steel is 7850 kg/ m3)
= 22.765 kg
