The membrane hinge was too light to be detected by the scale. An estimate was therefore made based on the size ratio between membrane and hinge according to calculated mass of 16.8. The primary discrepancy between calculated and weighed values is found in the mass of the membrane.

Mass: Initial estimates
Parameter Calculated mass (kg) Weighed mass (kg)
M a 1.2 × 10−5 1.3 × 10−5
Mm Mh 3.2 × 10−6 6.0 × 10−6
M h 1.9 × 10−7 3.6 × 10−7
M c 3.2 × 10−4 3.0 × 10−4
M b 1.6
