According to , the complexity of mechanical and electrical systems and applications of vibratory equipment in them have increased markedly in recent years. For example, vibration is put to work in vibrating power tools like jackhammers and chainsaws, vibratory feeders and conveyors, hoppers, sieves, electric toothbrushes, dentist’s drills, mobile phones, including the fitness machines in recent times .
