← HistoryWhich effect results when excessive ornamentation adds weight to a medieval Islamic brass astrolabe's alidade?
A)Parallax errors worsen noticeably✓
B)Limb graduations become unreadable
C)Ecliptic ring rotations stiffen
D)Local time estimations improve
💡 Explanation
Increased alidade mass causes greater instrument flex due to beam bending, imparting angular measurement errors because gravitational effects on alignment are magnified; therefore parallax worsens, rather than enhancing readings, due to deformation under load.
