Moment of inertia of at section. Area moment of inertia or moment of inertia for an area also known as second moment of area i is a property of shape that is used to predict deflection bending and stress in beams. Each calculator is associated with web pageor on page equations for calculating the sectional properties. Then this moment of inertia is transferred about the axis passing through the centroid of the given section using theorem of parallel axis.

The moment of inertia of a body with the shape of the cross section is the second moment of this area about the axis perpendicular to the cross section weighted by its density. Sub area a consists of the entire web plus the part of the flange just above it while sub area b consists of the remaining flange part. When calculating the area moment of inertia we must calculate the moment of inertia of smaller segments.

However since the flanges are equal a more straightforward combination can be a b c 2v 2v. This is also called the polar moment of the area and is the sum of the second moments about the x displaystyle x and y displaystyle y axes. The moment of inertia of a tee section can be found if the total area is divided into two smaller ones a b as shown in figure below.

Area moment of inertia imperial units. 1 in 4 4 16x10 5 mm 4 41 6 cm 4. This will calculate the centroid moi and other results and even show you the step by step calculations.

The following links are to calculators which will calculate the section area moment of inertia properties of common shapes. The moment of inertia of the rectangles is determined about its centroid. Try to break them into simple rectangular sections.

Area moment of inertia metric units. The moment of inertia of an i h section can be found if the total area is divided into three smaller ones a b c as shown in figure below. Segment the beam section into parts.
