WebArea moment of inertia is also known as the second moment of an area for a reason. It can be calculated by taking moment about the area twice i.e., Second moment of area = (area) x (perpendicular distance)2. The perpendicular distance depends on the axis of bending. The following are the generalised formula for area moment of inertia. WebPractice: The moment of inertia for a single object is given by the formula I = mr 2. When there are multiple objects, the total moment of inertia is the sum of the individual moments. A.
