Which navigational risk increased when wooden-frame sextants replaced brass?

💡 Explanation

Thermal expansion sensitivity increased the risk of drift because wood has a much larger coefficient of thermal expansion than brass; therefore calibration becomes unreliable with temperature swings, rather than the graduations wearing down or other optical defects.

• Which optical effect enabled Alhazen (Ibn al-Haytham) to more accurately describe refraction through curved lenses?
• What Byzantine defensive consequence resulted when poorly maintained Greek fire siege engines exceeded pressure limits?
• Which risk increases when Viking longship rigging experiences hysteresis?
• Which vulnerability exposed during Roman sieges with ballistae increased risk of defensive structure collapse?
• Which outcome occurred when Al-Khwarizmi established foundational algebraic principles using geometric proofs?
• Which outcome arose after innovations altered the properties used for Byzantine silk armor laminates under stress?
