History

Which outcome increased navigational error correlating azimuth angles when ocean swells perturbed early mariner astrolabes?

A)Gear train wear rate rises
B)Friction damping effectiveness declines
C)Inertial measurement precision degrades
D)Metal fatigue crack growth accelerates

💡 Explanation

The astrolabe’s accuracy decreases because inertial measurement precision degrades affecting its ability to maintain stable angular references during ocean swell. This occurs due to increased acceleration, therefore accuracy is lower rather than from purely mechanical wear or structural failure.
