These medical and paramedical specialists usually do not have a strong mathematics and physics background. Biomechanics must be presented to these professionals in a rather nonmathematical way so that they may learn the concepts of mechanics without a rigorous mathematical approach. On the other hand, many engineers work in fields in which biomechanics plays a significant role. Human factors engineering, ergonomics, biomechanics research, and prosthetic research and develo...
