Which consequence arises when a Roman siege ramp's angle exceeds design limits?

💡 Explanation

Excessive siege ramp incline leads to gravitational instability; the mechanism is increased shear stress within the earthen structure. Therefore, collapse risk increases, because the internal friction may be insufficient; rather than improving infantry movement due to overly steep terrain.

• Which structural risk increased with multistory aqueducts such as the Pont du Gard by overlapping arches?
• Which consequence results when a dense concentration of defenders exceeds the design limits of piled earth siege ramparts during an attack?
• Which risk increases when a Roman aqueduct's settling tank experiences turbulent inflow?
• Which risk increased for the pre-Columbian Maya civilization when terraces built for maize cultivation experienced prolonged rainfall?
• Which outcome accompanied gunpowder refinement during Song Dynasty China?
• Which factor most limited the accuracy of calculating time or celestial positions using medieval astrolabes?
