Which consequence resulted from brass sextant frame warping aboard 18th-century ships?

💡 Explanation

Inaccurate navigation stemmed from thermal expansion warping the brass; this deformation misaligns mirrors, causing systematic angle errors because the sextant's reflective measurements rely upon precise frame geometry; therefore angles were incorrect, rather than affecting unrelated chronometer functions.
