Which structural problem occurred because Medieval masons unknowingly exceeded compressive strength of stone?

💡 Explanation

Increased lateral thrust occurred, because exceeding the stone’s compressive strength caused shear stress leading to cracking. Resultant arch walls then spread under load due to insufficient buttressing, therefore lateral thrust increased, rather than just keystone slippage or subsidence common with poor foundations.
