In early Islamic astronomy, which outcome resulted from increasing the diameter of an astrolabe's limb?

💡 Explanation

The increased limb diameter provides a longer arc length for each degree marking, thereby increasing angular measurement resolution because the *vernier scale* mechanism spreads divisions across a larger space; therefore, accuracy increases rather than decreasing portability which is a different concern.

• Which limitation to resolution occurred in medieval astrolabes focusing on distant landmarks?
• Which outcome arose from reduced Tigris-Euphrates alluvial deposition in ancient canal systems?
• Which outcome commonly resulted when pre-Columbian chinampa farmers unknowingly introduced excessive nutrients?
• Which physical failure limited the scale of early Mesopotamian bronze tools despite wide availability of copper and tin?
• Which navigational risk decreased significantly, following adoption of Harrison's chronometers?
• Which risk increased on 18th-century wooden warships primarily due to the galvanic corrosion mechanism?
