Web Vibration occurs in two forms Whole body Hand Arm Whole Body Vibration Whole body vibration is caused by standing or sitting on vibrating surfaces which in turn causes muscle contractions and fatigue The vibration works its way through the body and results in muscle fatigue and contractions
Vibration Wikipedia, Web Vibration from Latin vibr to shake is a mechanical phenomenon whereby oscillations occur about an equilibrium point The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road
Vibration Physics Frequency amp Amplitude Britannica
Web Vibrations fall into two categories free and forced Free vibrations occur when the system is disturbed momentarily and then allowed to move without restraint A classic example is provided by a weight suspended from a spring In equilibrium the system has minimum energy and the weight is at rest
Physics Tutorial Vibrational Motion, Web Wiggles vibrations and oscillations are an inseparable part of nature A vibrating object is repeating its motion over and over again often in a periodic manner Given a disturbance from its usual resting or equilibrium position an object begins to oscillate back and forth In this Lesson the concepts of a disturbance a restoring force and damping are discussed
