WebMoment of Inertia--Earth The Earth is roughly an oblate spheroid, with the bulge occurring at the equator. Let A be the moment of inertia along an equatorial axis, and let C be the moment of inertia about the polar axis. Then Lambeck (1980) gives while Stacey (1977) … WebIn the limit that the moment of inertia goes to zero, the torque needed to accelerate (or decelerate) the body tends towards zero. It means that if there were no inertia (more precisely, when it tends towards zero) the spin of the Earth could increase or decrease arbitrarily fast even for external torque approaching zero. cpa chemicalWeb1 sep. 1991 · Let the Earth's equatorial principal moments of inertia be A and B, where A < B, and the corresponding principal axes be a and b.

WebIts radius is 6.36 * 10^6 m. Calculate the moment of inertia of planet Earth. The density of the Earth, at any distance r from its center, is approximately (14.2-11.6(r/R)*10^3) Kg/m^3, where R is the radius of the Earth. Show that this density leads to a moment of inertia I = Find the moment of inertia of the earth. Web19 dec. 2024 · The Moment of Inertia is a measure of an object’s resistance to changes to its rotation. Also it can be defined as the capacity of a cross-section to resist bending. It measures its resistance to the action of a torque about the same axis and i t must be specified with respect to a chosen axis of rotation and It is usually quantified in m4 or ...
