Which outcome results when attempting to accelerate a loaded Roman water wheel beyond its design speed?

💡 Explanation

When a water wheel exceeds designed speed, the overshot buckets empty prematurely because the water's momentum carries it over, thus reducing the torque applied to the wheel. Therefore, overshot flow reduces torque, rather than efficiency increase, friction reduction, or resonance which require different operating conditions or failure modes.
