Chapter 2 Basics of Vibration Dynamics Vibrations are mechanical oscillations about an equilibrium position. There are cases when vibrations are desirable‚ such as in certain types of machine tools or production lines. Most of the time‚ however‚ the vibration of mechanical systems is undesirable as it wastes energy‚ reduces efficiency and may be harmful or even dangerous. For example‚ passenger ride comfort in aircraft or automobiles is greatly affected by the vibrations caused by outside disturbances

Video games‚ are they good? Are video games a distraction or an angel in disguise? New studies show that video games are actually really good for you. Playing video games can increase eye hand coordination‚ decision making‚ and self-confidence. Dr. Daphne Bavelier‚ a neuroscientist at the University of Geneva‚ has conducted research on the effects of video games on the brain. Her research shows that video games actually help gamers focus (and maintain focus) better than non-gamers - more

CLASSIFICATION OF VIBRATION Vibration can be classified in several ways. Some of the important classifications are as follows. • Free Vibration. If a system‚ after an initial disturbance‚ is left to vibrate on its own‚ the ensuing vibration is known as free vibration. No external force acts on the system. The oscillation of a simple pendulum is an example of free vibration. • Forced Vibration. If a system is subjected to an external force (often‚ a repeating type of force)‚ the resulting vibration is known
