Statement of the Problem: Scientists study gyroscopic effects without success for over 300 years. Only famous L. Euler derived a mathematical model for the precession torque that does not explain other gyroscopic effects. Recent studies demonstrated; the physics of gyroscopic effects are more sophisticated than contemplated by researchers. Methodology & Theoretical Orientation: The external torque acting on the spinning objects generates the system of inertial torques with the feedback system and interrelated motions around axes presented in the coordinate system (Fig. 1)) where the external torque (bold line), the inertial torques (thin line), and the angular velocities of the disc (contour line). The action of the torques and interrelated motions of the spinning disc was defined by the method of causal investigatory dependency. Findings: The inertial torques acting around axes are produced by four centrifugal and two Coriolis forces and the two changes in the angular momentum are generated by the rotating mass of the spinning disc. The action of the inertial torques generates interrelated motions of the spinning disc around axes. Conclusion & Significance: The system of torques and interrelated motions of the spinning disc around axes make up the fundamental principles of the theory of gyroscopic effects for rotating objects based on the mechanical energy conservation law. These fundamental principles open a new chapter in the dynamics of rotating objects in classical mechanics that should be presented in all publications of physics mechanics.
Dr. R. Usubamatov studied Mechanical and Manufacturing Engineering at Bauman Moscow State Technical University, graduated as a professional engineer in 1966, and received his Ph.D., in 1972. After several years of postdoctoral research, he obtained the degree of Dr. Tech. Sc, at the Kyrgyzstan Academy of Sciences. He was an engineer at the Bishkek Engineering plant in Kyrgyzstan and worked at the Razzakov Kyrgyz State Technical University. The political and economic crisis in Kyrgyzstan forced him to migrate and work for 15 years at universities in Malaysia. He has published over 400 research manuscripts in journals, 8 books, and 60 patents of inventions. His fundamental books are "Productivity Theory for Industrial Engineering", Taylor & Francis, 2018, London, New York, Boca Raton, and "Theory of Gyroscopic Effects for Rotating Objects", 2nd ed. Springer, Cham, Switzerland, 2022. He is a member of international scientific associations and the EBM for international journals.
