← HistoryWhich limit during geared astrolabe construction posed substantial challenges due to complex calculations?
A)Achieving accurate arcuate scale divisions✓
B)Ensuring consistent brass alloy ratios
C)Measuring celestial observational altitude
D)Maintaining level instrument gravitational balance
💡 Explanation
Producing accurate arcuate scale divisions, notably for the ecliptic, was problematic because the required nonlinear angular spacing necessitated algebraic approximations or iterated geometric solutions rather than simple linear scaling; therefore, precision was challenging because of error propagation.
