History

Which mechanical failure was prevalent in early Mesopotamian bronze agricultural plowshares during abrasive soil tilling?

A)Brittle fracture from thermal cycling
B)Erosion from tribochemical wear
C)Creep deformation under sustained stress
D)Galvanic corrosion accelerating failure

💡 Explanation

When early bronze plowshares tilled soil, tribochemical wear occurred because minerals in the soil reacted chemically in the presence of friction, accelerating surface material removal from the bronze alloy. Therefore erosion prevailed, rather than fracture, creep or galvanism which require differing environmental or material conditions.
