Why study vibration?
The ultimategoals of this study are to determine the effect of vibration on the performance and safety of systems, and to control its effects. With the advent of high per- formance machines and environmental control, this study has become a part of most engineering curricula. text presents the fundamentals and applications of vibration theory.
What is Newton’s equation for the vibration of a spring?
Considering first the free vibration of the undamped system of Fig. 2.4, Newton’s equation is written for the mass m. The force m¨x exerted by the mass on the spring is equal and opposite to the force kx applied by the spring on the mass: m¨x + kx = 0 (2.4) where x = 0 defines the equilibrium position of the mass.
