## Segment Torque about Origin

Once segmental center of mass positions are known, these can be used with the segment
mass percents to determine a "torque" about an axis. This is really a
(mass)*(length) calculation.

If the torques created by each segment are summed the result is equal to the torque of
the whole body mass acting at the center of mass location. This idea allows determining
the unknown whole body CM location.

In your spreadsheet, add a column with the segement mass percents. Then write formulas
for each segment's torque in each direction. Finally, sum the torques and divide by total
body mass (100%).
