Moment of inertia of a shape
Webmoment of inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered … WebTo find the moment of inertia, divide the area into square differential elements d A at ( x, y) where x and y can range over the entire rectangle and then evaluate the integral using double integration. 🔗 🔗 The differential element d A has width d x and height , d y, so . (10.2.1) (10.2.1) d A = d x d y = d y d x. 🔗
