Which outcome resulted from attempting to fabricate astrolabes from brittle speculum metal?

💡 Explanation

Using brittle speculum metal causes catastrophic cracking during the shaping process because increased hardness causes low fracture toughness therefore resulting in inaccurate angular scales, rather than improved corrosion resistance given its composition.

• Which consequence resulted from Vitruvius's road alignment deviations?
• Which outcome increased water damage to Roman concrete?
• Which risk increases when Roman concrete (opus caementicium) is exposed to seawater for extended periods?
• Which consequence occurred when repeated chinampa construction disrupted the native hydrology?
• Which functionality degradation occurred when medieval astrolabes experienced thermal expansion in desert climates?
• Which environmental risk increased when pre-Columbian societies intensified terrace farming in the Andes?
