Which challenge was addressed when creating early cast iron plows in 18th-century America?

💡 Explanation

Brittle fracture was a significant problem because gray cast iron, a material commonly used in plows, has low tensile strength; therefore, processing techniques of quenching created tougher plow shares rather than shattering under soil stress, which increases wear.
