← HistoryWhich risk increases when an astrolabe's mater warps due to temperature changes?
A)Accuracy of time calculations reduces✓
B)Instrument weight becomes imbalanced easily
C)Alidade pointer detaches prematurely
D)Rust formation on limb accelerates greatly
💡 Explanation
Reduced accuracy results because thermal expansion causes misalignment of engraved coordinate lines; this positional error affects angular measurements when using stereographic projection, therefore temporal calculations become unreliable rather than just weight imbalance alone arising or rust.
