Explore the area moment of inertia (second moment of area) with detailed formulas, calculation tools, and reference tables for common shapes. Essential for structural and mechanical engineering applications.
The moment of inertia varies depending on the shape and size of the object. For simple geometric shapes, such as cylinders, spheres, or rectangular solids, there are specific formulas to calculate their moments of inertia. For more complex objects, the moment of inertia can be found by integra...

First, the moment of inertia is proportional to the mass of the body. All other things being equal, the moment of inertia increases or decreases in direct proportion to the body's mass. We can prove that I and M are proportional if we can show that increasing one by a factor of 2 ...
Knowing the six quantities Ix, Iy, Iz, Ixy, Iyz, and Izx, we can successively calculate, using formulas (4) and (3), the entire set of moments and products of inertia of a body with respect to any axis. These six quantities define the inertia tensor of the body. Through each point...

Second Moment of Area, Area Moment of Inertia The Area Moment Of Inertia of a beams cross-sectional area measures the beams ability to resist bending. The larger the Moment of Inertia the less the beam will bend. The moment of inertia is a geometrical property of a beam and depends on ...
It can be found by integrating over the mass of all parts of the object and their distances to the center of rotation, but it is also possible to look up the moments of inertia for common shapes. The torque on a given axis is the product of the moment of inertia and the angular ...
