Trapezoid Section Equation UsedDescription 
Equation

Area Moment of Inertia Section Properties I_{x} (in^{4}, mm^{4}) = 
bh^{3} / 36 
Area Moment of Inertia Section Properties I_{x'} (in^{4}, mm^{4}) = 
bh^{3} / 12 
Area Moment of Inertia Section Properties I_{y} (in^{4}, mm^{4}) = 
(hb^{3} / 36) ( a^{2}  ab + b^{2} ) 
Distance to neutral axis y (in, mm) = 
h / 3 
Distance to neutral axis x (in, mm) = 
( a + b ) / 3 
Area A (in^{2}, mm^{2}) = 
bh / 2
