Abstract
A computerized model of the human body is developed. It assumes the skeletal muscle system to be analogous to a series of eight solid links representing the major body segments which are articulated in a manner corresponding with selected body joints. It is shown by empirical tests that the model can be used to predict the maximum strengths of persons asked to lift objects while assuming different postures. It is proposed that this type of model represents a rational method for investigating the many variables that affect the physical strength capability of any individual required to perform materials-handling activities.
