What outcome occurred from metallic impurities interfering with 18th-century brass sextant manufacturing?

💡 Explanation

Inclusions caused inconsistent Thermal expansion. This caused inaccuracies in angle measurement because the brass expanded non-uniformly with temperature changes during celestial sighting. Therefore measurements are off relative to true position; rather than simple corrosion influencing use.

• Which consequence results when the angle of the herringbone brick pattern is improperly set on the Mughul era garden aqueduct system?
• Which consequence results when incorrect positioning of Inca stone masonry?
• Which risk disproportionately increased for Mesopotamian bronze tools used in hot arid climates compared to temperate ones?
• While using a historical astrolabe at sea, imprecise leveling of the instrument introduces which effect?
• Which risk intensified with the emergence of larger, more elaborate dry-stone retaining walls used during the Inca empire?
• Which effect arises when Medieval Islamic astronomers used spherical astrolabes closer to the magnetic poles?
