Document Summary
Biomechanics: all forces, both external and internal, responsible for movement. Production depends on the muscles abilities to generate tension. Ergonomics: the investigation of design for facilities, tools, and tasks that match human capabilities. The laws of work built around human function. Wsmds are also knows as: repetitive strain injuries, overuse injuries. Risk of injury depends upon: duration and/or frequency and/or intensity of exposure. There are things we can do to decrease. Pitchers shoulders rotators cuff tendonitis and bursitis. Carpal tunnel syndrome: big in 50s, 60s, before keyboards came out. Carpel tunnel syndrome: median nerve is compressed at the wrist, resulting in numbness or pain. Examines the causes of motion: internal and external forces that cause motion (or rest). There are two branches of kinetics: statics and dynamics. Statics: situations where the body or object remains at rest, or is moving at a constant speed in a state of equilibrium. Dynamics: deals with changes in motion brought on my unbalanced forces.
