Matrix supercomputer mathway free online calculator.How to calculate moment of inertia about any axis? What if the origin of the coordinate system does not coincide with the centroid? Don't worry - the second moment of the region can still be found! You need to use the parallel axis theorem. Suppose you want to find the Area moment. You need to use the following formula: I = Ix + Aa² Where: I is the moment of inertia about an axis parallel to the x-axis, Ix is the moment of inertia about the x-axis, A is the area, and a is the distance between two parallel axes. To find the area of ​​a circle (and its other properties), use the perimeter calculator. Example: moment of inertia of a rectangle We assume a rectangle with a width of 12 cm and a height of 8 cm. Its center of mass is at the origin of the coordinate system. Then: Ix = 12 * 8³ / 12 = 512 cm⁴ Iy = 8 * 12³ / 12 = 1152 cm⁴
