WebLet’s assume a dm mass on the shell; we will calculate the moment of inertia of this dm mass and then integrate it later to obtain the moment of inertia for the complete sphere. dI = dMR². dM = dA. dA = R dθ × 2πR. Thickness = R dθ. Circumference = 2πR. sin θ = r = R sinθ. We know A = 4R². WebThe unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square. In the U.S. customary system, m is in slugs (1 slug = 32.2 pounds) and r in feet, with I expressed in terms of slug-foot square.
