Circular area moment of inertia
WebQuestion: 2. \( [15 \mathrm{pt}] \) (a) Using the parallel-axis theorem, determine the product of inertia of the area shown with respect to the centroidal \( x \) and \( y \) axes. (b) Draw the Mohr's circle and represent the moments and product of inertia on it. (c) Using the Mohr's circle, determine the moments of inertia and the product of ... WebFeb 20, 2024 · The area moment of inertia, also called the second moment of area, is a parameter that defines how much resistance a shape (like the cross-section of a beam), has to bending because of its geometry. Consider a thin plank that supports a 100 kg load. The plank will be much less stiff when the load is placed on the longer edge of the cross-section.
