Deriving moment of inertia
WebThe spacecraft is axisymmetric and its principal moments of inertia of both the spacecraft and the wheel together are J t = J x = J y = 4. 83 kg · m 2, J a = J z = 0. 044 kg · m 2 (i.e., same as the original Explorer-I). The moment of inertia of … The moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration. It depends on the body's mass distribution and the …
