Which structural challenge did Roman arch builders overcome using voussoirs and keystones in aqueducts?

💡 Explanation

When arches are loaded, voussoirs transfer compressive forces because the wedge shape converts vertical load into lateral pressure, with the keystone locking the structure. Therefore minimizing tensile stress results, rather than maximizing flow, preventing sediment, or reducing thermal effects, which are related to water properties and temperature.
