Which failure frequently undermined Roman siege ramp efficacy during the Republic?

💡 Explanation

Soil subsidence around the earthen ramp failed due to differential compaction because the ramp's weight exceeded foundation's bearing capacity, therefore decreasing height and disrupting the siege rather than crew or projectiles, because the effect is due to distributed load.

• What limited ship size using 18th-century carvel construction?
• Which outcome occurred from chronometer drift aboard 18th-century Royal Navy ships?
• Which distortion increases when a medieval convex lens deviates from ideal sphericity?
