Question

Bio-mechanics?

Answer 1

Are you asking what biomechanics is? A few more words in the question wouldn't go amiss but here goes.

BioMechanics is the study of forces, moments and motions involved in moving biological systems. This can be human or animal bodies (where bones may be treated as rigid bodies with inertia and muscles as acutators) or on smaller scales for such things as protein folding.

As in traditional mechanics one is generally interested in dynamics (where forces are determined for / from a particular motion) or kinematics (where motion of individual joints combine to locate the body in space). In forward simulation the operator inputs the data to see the resulting motion, in inverse simulations the operator is interested in determining what forces / joint angles are required for a particular motion.

A great deal of biomechanics currently focuses on the use of motion capture systems where data can be inferred from the motion of subjects tracked in 3D space with several high speed cameras detecting reflective markers placed on the subject's body. One example is for studying gait in order to determine walking techniques in disabled persons.
