← HistoryWhich destructive outcome reliably occurred when medieval castle walls exceeded design constraints?
A)Reinforced mortar underwent accelerated hydration
B)Internal tensile stress exceeded material strength✓
C)Wooden scaffolding prematurely decayed
D)Attacking trebuchets experienced catastrophic failure
💡 Explanation
Catastrophic wall collapse occurred because exceeding height limits introduced excessive tensile stress; the material (stone/mortar) could not withstand, therefore tensile failure occurred, rather than other modes influenced by environmental factors or external events.
