Which risk increased in Crusader castles when large trebuchets achieved accurate bombardments?

💡 Explanation

Undermining foundations became a major risk because sustained trebuchet fire induced stresses beyond soil bearing capacity. This is soil liquefaction; the ground loses strength because of increased pore pressure, therefore the structure settles unevenly rather than resisting the static load.

• Which structural weakness most affected 18th-century timber ship wall construction during sustained broadside cannon fire?
• Which outcome occurs when differential settling affects load-bearing ziggurats?
• When Song dynasty miners overused gunpowder in iron mines, which consequence most immediately threatened the mine structure?
• During naval sieges, which outcome occurred when Greek Fire canisters employed a limited-range deployment?
• Which forging outcome occurred during Ming Dynasty cast-iron cannon firing?
