Flange = 150 mm x 5 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
Volume of Web = 145 mm x 5 mm x 1 m …..(150 mm – 5 mm = 145 mm)
= 0.145 m x 0.005 m x 1 m
= 0.000725 m3
Volume of ‘T’ Section = Volume of Flange + Volume of Web
= 0.00075 + 0.001475
= 0.001475 m3
Weight of ‘T’ Section = Volume of ‘T’ Section x Density of steel
= 0.001475 x 7850...........(Density of steel is 7850 kg/ m3)
= 11.578 kg
