Rectangular plate moment of inertia formula
WebSince we have a compound object in both cases, we can use the parallel-axis theorem to find the moment of inertia about each axis. In (a), the center of mass of the sphere is located at a distance from the axis of rotation. In (b), the center of mass of the sphere is located a distance R from the axis of rotation. WebJan 21, 2004 · In this problem, take the center of the rectangle to be at (0,0) so the vertices are (a/2, b/2), etc. Then the distance from (x,y) to the axis of rotation (passing through (0,0)perpendicular to the plate) is √(x2+ y2) and the moment of inertia is [itex]\int_{-a/2}^{a/2}\int_{-b/2}^{b/2}\rho (x^2+ y^2)dydx [/itex]
