Figure 1: Area moment of inertia formulas for rectangular sections. The diagram shows the standard equations Ixx = bd³/12 and Iyy = db³/12, where 'b' represents width and 'd' represents depth of the cross-section about the centroidal axes.
Area Moment of Inertia
The area moment of inertia is a section property that provides resistance to deflections. Area moment of inertia, also referred to as the second moment of area, is an essential…
