According to given figure,
x = lxc + Ac (y1 - y)² + 1xw+Axw (Y-Y₂)²
x = (53.7 x 106) + 3929(460.6 - 296.66)² + (333 x 106)
+9450(296.66 - 228.5)²
x = (159.297 +376.903) x 106
x = 536.2 x 106 mm²
Now,
ly = lyc+lyw
ly = (1.61 x 106) + (16.6 + 106)
= 18.21 x 106 mm²
ly
A = 13379 mm²
x = 536.2 x 106 mm4
ly = 18.21 x 106 mm 4
