RESULTS
The best estimate mass model of MOR 693 (Figure 2,
Animation 1 and
Animation 2) has a total body mass of 1500.91
kg, with the whole body CM positioned 0.184 m and 0.141 m in front and below the acetabulum.
Table 1 summarizes the mass data for each of the initial gracile
and larger models produced in the sensitivity analysis, a suite of which can be
seen in the accompanying animations (Animation
3, Animation 4,
Animation 5,
Animation 6,
Animation 7,
Animation 8,
Animation 9, and
Animation 10. The largest model (Figure 3,
Figure 4,
Animation 9, and
Animation 10) represented an increase of 31.7% (457.94 kg) in total body mass over the best estimate prediction,
while the smallest model (Figure 3.1,
Animation 3 and
Animation 4) was 12.9% (193.22 kg) lighter than initial predictions (Table 1). Best estimate centre of mass positions were most affected by altering the combinations of body segment volumes; the combination of large thoracic and neck segments with reduced tail segments resulted in the most cranial CM positions (0.375 m in front of the acetabulum), while enlarged tails and reduced anterior body segments brought the CM closest to the acetabulum (0.05 m in front of the joint). However, the CM remained in front and below the hip joint in all models. The full mass set results for the model generated can be found in the appendix (Appendix: Tables 2-25).
