The moment of inertia is defined as the product of mass of section and the square of the distance between the reference axis and the centroid of the section. The moment of inertia I is also defined as the ratio of the net angular momentum L of a system to its angular velocity ω around a principal axis, that is WebSecond moment of area = area x (perpendicular distance)^2. Where, dA = area considered y = perpendicular distance taken from the X − axis to area dA x = perpendicular distance …
Web1. You have to use the moment of inertia of the spherical shells in your derivation, which is. d I = 2 3 r 2 d m = 2 3 r 2 d ( 4 π r 2 d r) Integrating this will give the correct answer. Remember, you're adding up the spherical shells, not individual point masses, so this changes the calculation. Share.
