Which navigational risk increased because 18th-century ship's metal sextant frames experienced thermal distortion at sea?

💡 Explanation

Thermal distortion in the sextant frame caused angle measurement error, inducing larger cumulative longitude errors; this is because the frame expanded or contracted with temperature. Therefore longitude error increased because of angular error, rather than affecting sailing performance or leaks.

• Within Inca suspension bridges, which failure mode accelerated when daily thermal cycling weakened plant fiber?
• Which mechanism allowed Incan terrace farming to lengthen growing seasons?
• Which outcome critically depends on hydraulic head within the Mughal garden water systems?
• Which risk increased for Inca record-keepers when environmental humidity rose?
• Which failure mode risked early suspension bridges when gusting winds matched structure's frequency?
• Within Mughal gardens employing intricate 'pietra dura', which risk escalates disproportionately when unfiltered river water feeds the fountain system?
