Which consequence results when an incorrect 'al-jabr' formulation flawed the intended structural arch design in 10th century Cordoba?

💡 Explanation

A flaw in the algebraic calculation would lead to incorrect arch geometry. The 'al-jabr' mechanism then produces a structurally unsound form, because the forces are improperly distributed; therefore collapse occurs, rather than stable load-bearing, and it results in instability due to poor geometry.
