This book deals with the problem of dynamics of bodies with
time-variable mass and moment of inertia. Mass addition and mass
separation from the body are treated. Both aspects of mass variation,
continual and discontinual, are considered. Dynamic properties of the
body are obtained applying principles of classical dynamics and also
analytical mechanics. Advantages and disadvantages of both approaches
are discussed. Dynamics of constant body is adopted, and the
characteristics of the mass variation of the body is included. Special
attention is given to the influence of the reactive force and the
reactive torque. The vibration of the body with variable mass is
presented. One and two degrees of freedom oscillators with variable mass
are discussed. Rotors and the Van der Pol oscillator with variable mass
are displayed. The chaotic motion of bodies with variable mass is
discussed too. To support learning, some solved practical problems are
included.
