Hi, James.

Thanks for your reply.

I just reckon the mass of the rest body except both legs which is very close to the one I use. Another finding is that the residual forces are not propotional to the increase of the pelvis mass, which means there is optimal pelvis mass to balance the experimental external force. If continuing to increase the mass of pelvis, the residual vertical force will start to increase, out of range again most likely.

Thanks,
Linjie
