... A rigid body is an object/systems of particles in which the interparticle distances are fixed and remain constant. The center of mass of a system is the point at which all the mass of the system may be considered to be concentrated. If g is constant, then the center of gravity is at the center of ma ...

Chapter 12 Equilibrium and Elasticity
... We say that an object is in equilibrium when the following two conditions are satisfied: 1. The linear momentum P of the center of mass is constant. 2. The angular momentum L about the center of mass or any other point is a constant. Our concern in this chapter is with situations in which P 0 and ...

Precession

Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes. (See section Astronomy below.)
