← HistoryWhen ambient temperature changes an astrolabe's components, which inaccuracy increases the most significantly?
A)Alignment of altitude scales✓
B)Concentricity of rotating discs
C)Etching of hour angle lines
D)Straightness of the alidade edge
💡 Explanation
Misalignment of altitude scales increases because differential thermal expansion changes the components' dimensions; therefore readings become skewed, rather than affecting concentricity directly due to averaging during element placement or etching precision.
