We can calculate the weight of this I – section in the same way as we calculated for U – section
Here, we will have to know the outer and inner edge dimensions.
Volume of the I – section = cross-sectional area × Length
V = A × L = (( X1 × Y1 ) – 2 × ( x2 × y2 )) × L
Where X1 is outer edge width, Y1 is outer edge height and x2 is inner edge width, y2 is inner edge height.
Let us consider a 1 m long I – section of outer edge width 60mm = 0.060m, outer edge height = 80 mm = 0.080 m and inner edge width 25 mm = 0.025 m , inner edge height = 40 mm = 0.040 m.
So, Volume of the I section = [ (0.060 × 0.080) – 2 × (0.025 × 0.040) ] × 1 = 0.0028 m3
Hence, mass of the I section = density × volume = 7900 × 0.0028 = 22.12 kg
In this way we can calculate the mass of an I section with different dimensions.
