Which outcome regularly occurred on 18th-century sailing ships when brass quadrant scales corroded?

💡 Explanation

Erroneous star angle measurements arose because galvanic corrosion caused metal loss weakening demarcation notches, making precise aiming inconsistent depending on the observer eyesight rather than structural instability because the scales weren't part of a load-bearing system, therefore accurate readings become inaccurate readings.

• Which navigational risk increased when chronometers experienced pendulum error?
• Which risk increases when pre-Columbian terracing lacks sufficient drainage?
• Which irrigation outcome occurred more readily around Mughal-era gardens built atop shallow inclines?
• Which structural risk increased during the iterative construction of Mesopotamian ziggurats due to the layered mud brick design?
• Which mechanism reduces soil erosion on terraces using pre-Columbian agriculture techniques?
• Water damage risks rise notably when subsurface Mughal garden runoff erodes the mortar beneath 'pietra dura' inlay panels, permitting what mechanism?
