Which tactic enabled Roman siege engines overcome early defensive walls constructed solely from loosely stacked stones,?

💡 Explanation

When impacting an unconsolidated stone wall, rapid concentrated impacts by siege engines like trebuchets generate dynamic force exceeding the stone bond strength, initiating dislodgement and collapse. Therefore, focused impacts, rather than incendiaries, tunnelling, or feints, is correct given this specific constraint of weakly-bonded stone structures.

• Which outcome arises when timber ships, during the 18th century, exceeded longitudinal strength limits during construction?
• Which vulnerability increased significantly for trebuchets during prolonged sieges due to rope degradation?
• Which environmental adaptation enables pre-Columbian Andean terraced fields to prevent widespread topsoil loss after heavy rainfall?
• Which optical effect explains how Alhazen improved acuity limits in the 'Book of Optics' circa 1021 AD?
• Which benefit results from the practice of regularly 'silt-layering' in chinampa agriculture?
• Which condition necessitates terraces incorporating specific drainage systems in pre-Columbian Andean agriculture?
