Biomechanics and Work 4/1/2009 Biomechanics and Work 04/01/2009 Pre-Lecture Note: Even though there are anthropometric charts, sometimes one will still have to come up with their own data. Why is biomechanics and why is it important to study? Webster says: “the mechanics of biological and especially muscular activity” (as in locomotion or exercise) Why biomechincs really important for everday life? $20 Billion Dollars worth of annual importance Injuries and lawsuits from injuries Note: Anthropometrics gives limitations. Chart: Total recordable non-fatal occupational injury and illness incidences rates by selected industries, 2004-2005 NIOSH Standards Used to determine which biomechanical motions used in a specific application (lifting) are more at risk for injury Equation Based: RWL = LC x HM x VM x DM x AM X FM x CM RWL – Recommended weight limit http://www.ccohs.ca/oshanswers/ergonomics/niosh/calculating_rwl.html LC – Load Constant - A set weight used for the purpose of the equation
