Web3.2.6 Radius of Gyration from Light-Scattering Data. A radius of gyration in general is the distance from the center of mass of a body at which the whole mass could be concentrated without changing its moment of rotational inertia about an axis through the center of mass. For a polymer chain, this is also the root-mean-square distance of the ... WebNov 4, 2024 · 1. Posted September 17, 2015. In a book the radius of gyration is defined as. "Radius of gyration may be defined as the distance from the axis of rotation of a mass point whose mass is assumed to be equal to the mass of the whole body and whose moment of inertia is equal to the moment of inertia of the body about the axis".
WebWhen this is analyzed in detail, you find that the gravity at any radius r less than R Earth will be linearly proportional to the distance from the center. Taking positive r as outward from the center of the Earth: This is the same form as Hooke's Law for a mass on a spring.

Let S be a solid with a continuous mass density function δ(x, y, z) at any point (x, y, z) in S. Then the center of mass of S has coordinates (ˉx, ˉy, ˉz), where ˉx = Myz M, ˉy = Mxz M, ˉz = Mxy M, where
