Biomechanics lab simulations for undergraduates

[John F. Pilger]

I am interested in a computer-based biomechanics simulation suitable
for undergraduate biology students. I now use a kinematic model to
collect basic data relating to vertebrate limbs (the foot). The lab
illustrates the effect of the placement of muscle origin and
insertion and joint position on speed mechanical advantage, force
mechanical advantage and work output. I'm looking to put a little
more zip into the exercise and to be able to enter measurements made
on vertebrate skeletons. Can anyone direct me to the appropriate
software, if available?
