Hi all,

I am trying to track down some information on the biomechanics and trajectory of a arm for my forensics Masters project on cast-off which is bloodstain pattern created when blood is flung from an object in motion, i.e a swinging weapon. I want to create a machine that will mimic the action of an arm swinging an object such as a pick axe, like a wood chopping motion, but haven't had much luck as yet.
Can anyone tell me whether a swinging arm has circular or approximately circular motion?? if not, any suggestions as to where i could find this information?

Thanks
