← HistoryWhich constraint limited the resolution of astronomical measurements achievable using astrolabes historically?
A)Material thermal expansion coefficients
B)Accuracy limits of gear cutting✓
C)Human eyesight angular resolution
D)Atmospheric refraction variations
💡 Explanation
Errors cutting the gears led to inaccuracies using the mechanical movements during astronomical measurements of the astrolabe stemming from geometric projection; therefore, gear-cutting limitations constrained resolution, rather than factors related to optics or the environment. Limited MEMS-type tech.
